A method of preserving and augmenting bone height and width immediately after tooth extraction for future dental implant placement.

Indications

  1. Prevention of alveolar ridge atrophy after tooth extraction
  2. Restoration of bony defects caused by infection, trauma, and/or traumatic extractions

Contraindications

  1. Sites where future implant placement is unachievable
  2. Medical conditions that preclude implant placement

Technique

  1. Preoperative antibiotics and chlorhexidine rinses are administered immediately prior to extraction.
  2. Atraumatic exodontia is performed to maintain the buccal cortical plate and septal bone (see Figure 4.3 in Case Report 4.1).
  3. All periapical and granulation tissue is curetted from the extraction site.
  4. The extraction site is copiously irrigated, and doxycycline paste is applied to the extraction socket walls for 5 minutes.
  5. A particulate grafting medium is placed and compacted within the defect.
  6. A collagen membrane is placed (see Figure 4.4 in Case Report 4.1) to stabilize the graft and to guide tissue regeneration. A resorbable figure-of-eight suture is used to secure the collagen membrane and to close tissue elevations.
