Implants Placed in Adolescents Followed for Up to 15.5 Years: A Retrospective Case Series.

Purpose: To evaluate the clinical outcomes of unsplinted implant-supported single crowns placed in adolescents, ages 10 to 19 years, and followed up from 5 to 15 years.

Materials And Methods: This retrospective case series evaluated the outcomes of implant-supported single crowns placed in adolescents between June 2002 and January 2015. The patients were treated with locking-taper connection implants under a two-stage rehabilitation technique.

Histological Analysis of an Implant Retrieved from a β-Tricalcium Phosphate Graft after 4 Years: A Case Study.

We describe the retrieval of a dental implant device that had been successfully osseointegrated for more than 4 years. After obtaining an informed patient consent, the device was retrieved for retreatment purposes from its position in a β-tricalcium phosphate (β-TCP) grafted sinus floor. The sinus floor augmentation, using β-TCP, had been performed in conjunction with the original implant placement, which in turn enabled the histological evaluation of specific regions of interest that were comprised of either grafted or native bone.

A retrospective radiographic study on the effect of natural tooth-implant proximity and an introduction to the concept of a bone-loading platform switch.

Purpose: The aim of this study was to evaluate the effect of tooth-implant proximity using an implant system with a double platform shift that was designed to load bone coronal to the implant-abutment cohort study was conducted between January 2008 and December 2009. The sample was composed of patients who had received at least one 5-mm-wide hydroxyapatite-coated single-tooth Bicon implant that had been placed adjacent to at least one natural tooth. Descriptive statistics and univariate and multivariate linear mixed-effects regression models, adjusted for multiple implants in the same patient, were utilized.

The effect of opposing structures, natural teeth vs. implants on crestal bone levels surrounding single-tooth implants.

Objectives: To evaluate the effect of opposing structures in crestal bone levels around single-tooth implants.

Materials And Methods: A retrospective cohort study design was conducted. Descriptive statistics, univariate and multifactor mixed-effects regression models, adjusted for multiple implants in the same patient were utilized to evaluate the effect of opposing structures in crestal bone levels after insertion of single-tooth replacements.

The survival of ultrashort locking-taper implants.

Purpose: To evaluate the performance of 5-mm-long implants.

Materials And Methods: A retrospective cohort study was conducted between January 2008 and December 2009. The sample was composed of patients who had received at least one 5-mm-wide, hydroxyapatite-coated Bicon implant.

The effect of implant size 5 × 8 mm on crestal bone levels around single-tooth implants.

Background: There is substantial evidence supporting the strain-induced biologic response of bone to mechanical load. Stress-related factors, such as implant size, have been associated with changes in crestal bone levels on dental implants. The purpose of this study is to evaluate the effect of an implant size, specifically 5 mm wide × 8 mm long (5 × 8), on peri-implant bone levels.

Extraction, immediate-load implants, impressions and final restorations in two patient visits.

Background: Since the advent of immediately loaded implants, patients have experienced shorter treatment times, reduced amount of surgical therapy, preserved gingival esthetics and the comfort and security of fixed prostheses. Practitioners have experienced less expense in the form of chair time and greater patient satisfaction.

Case Description: The authors present two cases in which, at the first clinical visit, they extracted maxillary incisors, placed hydroxyapatite-coated implants, took impressions for final restorations and stabilized the implants immediately with a fixed interim prosthesis.
