Influence of gingival phenotype on crestal bone loss at implants : A long-term 2 to 20-year cohort study in periodontally compromised patient.

Purpose: The aim of this long-term cohort study in periodontally compromised patients with implants was to analyze the correlation between gingival phenotype and peri-implant crestal bone loss, and between clinical measures and gingival phenotype.

Methods: Implant-supported single crowns and bridges were used to rehabilitate 162 implants in 57 patients. Patients were examined over a 2 to 20-year period on a recall schedule of 3 to 6 months.

Sonography in the diagnosis of peri-implant bone defects: An in vitro study on native human mandibles.

Aim: The aim of this study on native human cadavers was to compare clinical, sonographic, and radiological measurements of fenestrations, dehiscences, and 3-wall bone defects on implants.

Materials And Methods: The examination was carried out on five human mandibles. After the insertion of 27 implants, dehiscences (n = 14), fenestrations (n = 7) and 3-wall bone defects (n = 6) were prepared in a standardized manner.

Influence of Crown-to-Implant Ratio on Crestal Bone Loss at Implants with Single Crowns and Bridges: A 5- to 20-Year Long-Term Cohort Study in Patients with Periodontal Disease.

Purpose: To evaluate how the crown-to-implant (C/I) ratio affects the loss of crestal bone at single-crown implants and bridges in patients with periodontal disease.

Materials And Methods: A total of 39 patients treated for periodontitis were rehabilitated with 108 implant-supported single crowns and bridges. Each patient was examined over a 5- to 20-year period on a 3- to 6-month recall schedule.

Correlation between crestal bone loss and PPD at teeth and implants: a 5- to 20-year long-term cohort study in patients with treated periodontal disease.

Objective: The correlation between crestal bone loss at teeth and probing pocket depth (PPD) has been established. Whether these findings can also be applied to implants is not known. The objective of this study was to determine the correlation between crestal bone loss and PPD at teeth and implants.

Implants in GBR-Augmented Sites in Patients Treated for Generalized Aggressive Periodontitis: A 10- to 20-Year Prospective Case Series.

The aim of this case series was to evaluate implants inserted in bone after guided bone regeneration (GBR). Fourteen patients with generalized aggressive periodontitis (GAP) who had lost one or two maxillary teeth in the incisor or premolar region were enrolled in the study. Due to bone resorption, the lateral width and vertical height of the bone were insufficient for implant placement.
