The effects of hypnosis dental pain threshold
Introduction: The use of hypnosis has been increasingly advocated in oral surgery to obtain sedation and decrease pain perception, but no data are so far available on dental pain threshold….
Validation of visual analogue scale for anxiety (VAS-A) in dentistry
Objectives: The Visual Analogue Scale for Anxiety (VAS-A) has shown a significant correlation with Corah’s Dental Anxiety Scale (DAS), but a discordance of 28% has been found between the two…
Photoelastic analysis of two protocols for zygomatic implants
Purpose: The objective of this study was to analyse in vitro the stress distribution in craniofacial structures around zygomatic osseointegrated implants. Materials and methods: Synthetic polyurethane skulls replicas were used…
Influence of immunosuppression on osteointegration of titanium implants and bone strength
Aim: To provide scientific background from animal model for implant application in patients under immunosuppression. Materials and methods: Forty eight Wistar male rats in six groups were receiving: (1) (…
Microdialysis on dental implants
Aim: Microdialysis is an established method in brain research. Herewith samples from extracellular space can be collected. Aim of our study was to evaluate the concentration of growth factors and…
Evaluation of biochemically modified implant surfaces in an osteoporotic animal model
Aims: The chemical and biochemical modification of dental implant surfaces enables a new approach to influence the peri-implant bone formation. Bone formation in regions of reduced bone quality is of…
Intra-oral bone grafting of alveolar defects using autogenous scraped bone and in vivo bone regeneration techniques
Introduction: Intra-oral bone grafting is a common procedure used to reconstruct the alveolar ridge and enable rehabilitation with dental implants. Extensive alveolar bone loss can result from trauma, follow post-ablative…
Long-term successes and failures of autotransplanted premolars
Objective: To evaluate long-term successes and failures of autotransplanted premolars, followed up to 30 years. Materials and methods: This study investigated a consecutive group of 100 patients treated with autotransplantation…
Glucocorticoid induced osteoporosis in the jaw of the Berlin minipig
Aim: Incidence of osteoporosis in western countries is increasing due to demographic development. Osteoporosis is a potential risk factor for dental implants. There are different alternatives to induce osteoporosis in…
In vitro bioactivity of Ti6Al4V surfaces processed with Er:YAG laser at different parameters
Aim: To analyse in vitro bioactivity of Ti6Al4V surfaces processed with Er:YAG laser at different parameters. Materials and methods: Ti6Al4V discs ( Ø = 7 mm) were used. Five treatment…
