Facial trauma impacts patients significantly in the short term and leaves distressing deficits in esthetics and function that often must be addressed surgically. Dental implants are a means of regaining these losses in form and function and can be helpful adjuncts used to return patients as close as possible to their previous functional and esthetic state. In this review, we analyze the most up-to-date recommendations and techniques in managing defects secondary to facial trauma with advanced practices in oral implantology.

Dental implants are a critical element in the rehabilitation of patients with facial trauma who have lost teeth and supporting structures, by restoring function, esthetics, and quality of life. These defects can be debilitating for patients, both limiting speech and nutrition, and causing significant psychological harm due to esthetic compromise. Advancements in personalized implant planning, digital workflows, and prosthetic design have heightened the effectiveness of post-traumatic implant rehabilitation. Implant placement is considered a reliable and predictable option for replacing teeth and surrounding tissues lost due to trauma, with high survival rates and favorable patient-reported outcomes when appropriately planned and executed. ^,,,

Complex facial trauma often requires a multidisciplinary approach, including surgical stabilization of the original injury followed by reconstruction, bone grafting, orthodontic alignment, and prosthodontic planning to optimize implant positioning and long-term outcomes. ^,,, Appropriate treatment sequencing is critical in optimizing final restorations. Implants should generally be delayed in growing individuals to avoid complications such as infraposition. A thorough assessment of skeletal maturity and stabilization of the dental arch is critical before proceeding as any continued craniofacial growth can result in vertical discrepancies, particularly in adolescents. Implant infraposition is at the greatest risk in growing individuals; however, even adults over the age of 40 can be subject to implant infraposition with time, likely due to the very slow process of continuous eruption of natural teeth through life. ^,, Because of the need for skeletal maturity for implant placement, temporary prostheses and orthodontic retainers are helpful adjunctive tools to maintain space and occlusion during the intermediate phases. ^, Restorative planning in conjunction with orthodontists and restorative dentists is essential. Each patient’s treatment plan is unique in post-traumatic implant reconstruction and warrants a highly individualized approach. In skeletally immature patients, using removable appliances or single winged bonded prosthetics are useful until implant placement can be accomplished predictably. This can provide esthetic improvement until definitive treatment can be rendered.

The sequencing of treatment depends on the hard and soft tissue substrate available following a traumatic injury. Implant placement should be deferred until the teeth surrounding a traumatic defect can be assessed for signs of injury to appreciate the full extent of the damage. Serially endodontically testing teeth to appreciate a reliable pulpal diagnosis is necessary. Orthodontic treatment to correct and align tooth position and bone grafting may be indicated to correct malposition following splinting or subluxation and to facilitate the necessary 1.5 mm mesiodistal space between a tooth and implant and at least 1 mm facial wall bone thickness to support long-term stability. ^,

Specifically, timing of the surgical placement of dental implants is dependent on the integrity of tissues in the site that was impacted by trauma. For immediate implant placement within 24 hours of tooth loss, several parameters must be met including thick gingival biotype, intact socket walls with facial bone that is at least 1 mm in thickness, no infection at the site, and enough palatal and apical bone to provide primary stability. While these criteria may be challenging to meet in the setting of trauma, these factors are critical predictors of soft tissue stability and implant survival. Hirani and colleagues analyzed outcomes of immediate implant placement following anterior maxillary trauma in patients with intact socket walls and sufficient facial bone volume. Their 2-year survival rate of over 95% demonstrated that, in carefully selected cases with preserved vascularity and soft tissue architecture, implants may be placed immediately without the need for grafting. However, failures were strongly associated with infection and buccal plate loss, reinforcing that immediate placement remains an exception rather than the rule in the acute trauma setting. Overall, immediate placement of dental implants after trauma is feasible only in carefully selected cases, whereas early implant placement—within 6 to 8 weeks after trauma—remains the most common and predictable approach.

If bony walls are preserved, most implants can be placed early, within 6 to 8 weeks of the injury. This will allow for soft tissue closure of the affected site and facilitates often-necessary bone contour augmentation at the time of implant placement to optimize long term facial bone support. ^,,

If 3-dimensional (3D) imaging reveals poor bone quality or structure, delaying placement by 12 to 16 weeks can allow for additional bone remodeling and improved conditions for primary stability.

In cases of severe trauma, a prolonged placement approach is warranted to ensure appropriate time for remodeling of tissues within the site. An added benefit of a prolonged approach is to allow for a period of observation of adjacent teeth that may have also been subject to trauma from the inciting event.

Traumatic tooth fractures extending below the alveolar crest can cause teeth to become nonrestorable and require extraction. In cases of extensive coronal fracture or when complex reconstruction is planned, extraction of teeth with poor prognoses may be necessary to support a stable and predictable restorative outcome. In these cases, dental implants represent a predictable and long-term solution for restoring function and esthetics once the supporting bone and soft tissues have healed. The timing of implant placement after traumatic extraction depends on the integrity of the remaining alveolus and the presence of infection and can follow an immediate, early, delayed, or prolonged approach as described above.

The use of ridge preservation techniques—including particulate autograft, allograft, or xenograft materials covered by a resorbable collagen membrane—has been shown to maintain ridge dimensions, exclude soft tissue ingrowth, and optimize subsequent implant placement. When appropriate case selection and atraumatic surgical principles are followed, implant survival rates after trauma-related extractions are comparable to those in nontraumatized sites.

When immediate reimplantation of an avulsed tooth fails or is not feasible, dental implants become the definitive restorative approach once hard and soft tissue deficiencies are addressed. Often, the avulsion will result in a delayed pulpal pathology or internal or external resorption after reimplantation and if endodontic or restorative therapies are not adequate to manage the disease, extraction may be indicated ( Box 1 , Figs. 1–3 ). Long-term sequelae of dental avulsions can be root resorption or tooth ankylosis. Avulsion sites commonly require ridge augmentation before implant placement to restore sufficient bone volume ( Figs. 4 and 5 ), however procedures such as decoronation of an avulsed tooth can be useful alternatives that allow for continued development and support of the bony dimensions of the alveolus. If a previously avulsed tooth has ankylosed and implant placement is planned, decoronation of the tooth is an excellent option to preserve bone contour and drive bony tissue replacement of the dental root with hopes of reducing the need for grafting of the site in the future. Often, extracting ankylosed teeth can result in bone loss that is critical for a good dental implant outcome. Importantly, decoronation should only be attempted in cases of ankylosed teeth with no apical pathology. To perform a decoronation, a full thickness flap is raised, the ankylosed crown is sectioned just below the alveolar crest, the pulp chamber is debrided of tissue or root canal therapy contents to prevent foreign body reaction, blood is allowed to fill the pulpal chamber and the site is closed. Over the course of months to years, the remaining root will be resorbed by bone through mesenchymal cells that repopulate the denuded tooth root. These cells differentiate into osteoclasts and osteoblasts that in turn breakdown root dentin and lay down the bone in its place. Interestingly, this otherwise pathologic process is one that cannot be prevented, but it can be harnessed to preserve bone contour in avulsed teeth when implant placement must be delayed.

Given the high incidence of soft tissue scarring and mucogingival contraction following avulsion and subsequent surgery, soft tissue augmentation is frequently indicated to enhance peri-implant keratinized tissue width. Free gingival or connective tissue grafts (CTGs) may be performed concurrently with or before implant placement to ensure keratinized tissue support to maximize likelihood of long-term peri-implant health. Interestingly, dental implants immediately placed in sites of avulsed teeth exhibited a rate of over 95%, a rate rivaling that of implants placed into completely healed bone.

Significant alveolar bone loss following facial trauma often necessitates bone augmentation before dental implant placement, as natural bone regeneration is unable to replace extensive defects, especially in the setting of cortical bone loss ( Box 2 , Fig. 6 ). This challenge is common in oral and maxillofacial surgery and implantology, where restoring bone volume and architecture is critical for implant stability and long-term success. ^,,,, Bone augmentation is frequently necessary when there is significant loss of supporting structures such as alveolar bone and soft tissue. ^, 3D imaging is particularly useful in planning for bone augmentation and implant reconstruction after trauma. Bone grafting occurs for the vast majority of implants placed following trauma and approximately 40% of these sites undergo a dedicated grafting procedure before placement of the implant.

Bone grafting techniques include guided bone regeneration (GBR), block grafts (from intraoral or extraoral sites), the shell technique, sinus lift procedures, distraction osteogenesis, and innovative methods such as the box technique using 3D-preformed titanium mesh. Technique selection is defect-specific: horizontal defects may be managed with staged GBR, block grafts, or ridge expansion, while vertical defects often require staged GBR, block grafts, or distraction osteogenesis. ^,,,,, (see Box 2 , Figs. 7–9 ).

Grafting materials include autografts, the gold standard for osteogenic potential, allografts, xenografts, and synthetics. Autografts remain the only graft type that is able to express the 4 principles of osteogenesis, osteoinduction, osteoconduction, and osseointegration to drive new bone formation. ( Box 3 ).

Although autografts provide superior biocompatibility, osteoinductive capacity, and adequate corticocancellous structure for reconstructing large defects, their use is limited by donor site morbidity, variable bone quality, and restricted availability. Autologous grafting is typically indicated for defects greater than 5 mm in thickness. Common areas that can be used for autologous grafting are cortical block grafts from the ascending ramus of the mandible, calvarium, tibia, or anterior and posterior iliac crest bone grafts (see Box 3 , Figs. 10–15 ). Cancellous bone affords greater bone turnover but is less dense, where cortical bone block grafts take longer to osseointegrate due to the denser composition and more limited turnover.

Mandibular ramus block grafts can be an excellent option for bone augmentation of up to 4 mm thickness for a span of up to 4 teeth and are highly accessible to the oral and maxillofacial surgeon. This technique exhibits about 10% risk of temporary, and a very low risk of permanent, inferior alveolar nerve paresthesia. ^,

Allografts and xenografts, for example, cadaveric cortical/cancellous bone and bovine-derived materials, have become integral components of alveolar and maxillofacial bone reconstruction, particularly in trauma patients undergoing staged implant rehabilitation. These materials provide osteoconductive scaffolds that facilitate new bone formation while obviating the need for autogenous harvest, thereby reducing donor site morbidity, operative time, and postoperative discomfort. ^,

In maxillofacial trauma, where bone loss often coexists with contamination, irregular defect geometry, or soft tissue compromise, the use of processed allogeneic bone offers both biological compatibility and mechanical versatility. Demineralized freeze-dried bone allograft retains limited osteoinductive potential via bone morphogenetic proteins, whereas mineralized allograft and cortical struts provide structural integrity and serve as stable osteoconductive frameworks for particulate grafts or implant anchorage. The combination of particulate allograft with cortical allogeneic plates has demonstrated favorable contour control and volumetric maintenance, effectively mimicking autograft performance without additional donor morbidity.

Xenografts, commonly derived from bovine or porcine sources, serve a complementary role by providing long-term volumetric stability and resistance to rapid resorption. Their deproteinized, inorganic composition results in high biocompatibility and strong osteoconductive properties, making them valuable in sinus elevation, alveolar ridge preservation, and post-traumatic contour restoration. When used alone, xenograft materials require significantly longer turnover time and exhibit incomplete osseointegration with more residual particles left even after extended healing time. The slow resorption kinetics of xenograft materials allow for sustained maintenance of graft volume during the extended healing period often required in trauma patients. For these reasons, xenografts should only be used alone in areas where bone bulk is needed, but where functionally dense bone is not as critical. When combined with allograft granules in a composite mixture, xenografts enhance dimensional stability while the allograft accelerates early remodeling, yielding a biologically active yet structurally stable graft bed.

Synthetic grafting materials are uniquely derived from various chemical substrates such as calcium phosphate ceramics such as hydroxyapatite, tricalcium phosphate and bioglass, metals, such as nickel-titanium, polymers, such as polymethylmethacrylate, and polyglycolides and calcium phosphate cements. These materials only exhibit osteointegrative and osteoconductive potential, and are often qualitatively brittle, which can compromise ideal regenerative capacity. Despite this, some of the synthetic materials, namely the biphasic calcium phosphate ceramics, bioactive glasses, and polymers have shown early promise as evaluated in clinical trials for grafting periodontal and furcation defects.

Membrane selection often falls into resorbable and nonresorbable options. Resorbable collagen-based membranes and nonresorbable options that can be made from polytetrafluoroethylene or metallic mesh are excellent options for bone grafting procedures and all result in excellent bone generation when appropriately used. Resorbable membranes are useful as they do not require a second surgery for removal, are biocompatible, and are relatively easy to use. Resorbable membranes lack the strength and structure needed for more substantial vertical and horizontal defects. While titanium mesh and tenting screws can offer the enhanced strength, structure, and stability required for these more challenging defects, they do require a second surgery for removal and can have complications due to tissue dehiscence over the site. ^, Crib grafts are generally reserved for only the most severe defects due to the degree of surgical intervention required. In cases with defects so significant that they require the support of titanium mesh or cribs, biologic adjuncts are often critical in attempting to facilitate bone formation in these challenging cases. ^, Ragucci and colleagues presented a case illustrating the use of a patient-specific computer-aided design/computer-aided manufacturing (CAD/CAM) titanium mesh scaffold for post-traumatic alveolar reconstruction. The customized design permitted precise adaptation to native contours, preserved soft tissue tension, and minimized exposure risk. At 12-month follow-up, the reconstruction demonstrated excellent volumetric stability and esthetic integration, highlighting the emerging synergy between digital planning, additive manufacturing, and synthetic biomaterials in oral and maxillofacial reconstruction.
