Marginal bone maintenance around implants placed in subcrestal level: a 2 to 9 years retrospective study

Marginal bone loss around implants placed in maxillary native bone or grafted sinuses: a retrospective cohort study.

OBJECTIVES To assess differences in marginal bone loss around implants placed in maxillary pristine bone and implants placed following maxillary sinus augmentation over a period of 3 years after functional loading. MATERIAL AND METHODS Two cohorts of subjects (Group 1: Subjects who received sinus augmentation with simultaneous implant placement; Group 2: Subjects who underwent conventional im...

Evaluation of Marginal Bone Level around Platform - Switched Implants

Purpose: The long-term success of an implant depends on the stability of bone support for the implant. Most crestal bone loss occurs in the first year of implant placement. Platform-switching is an approach which can be clinically applied to preserve the crestal bone. The concept of ‘platform switching’ refers to the use of a smaller-diameter abutment on a larger-diameter implant collar. The pu...

A short-term clinical study of marginal bone level change around microthreaded and platform-switched implants

PURPOSE The marginal bone levels around implants following restoration are used as a reference for evaluating implant success and survival. Two design concepts that can reduce crestal bone resorption are the microthread and platform-switching concepts. The aims of this study were to analyze the placement of microthreaded and platform-switched implants and their short-term survival rate, as well...

Bone-Implant Contact around Crestal and Subcrestal Dental Implants Submitted to Immediate and Conventional Loading

The present study aims to evaluate the influence of apicocoronal position and immediate and conventional loading in the percentage of bone-implant contact (BIC). Thus, 36 implants were inserted in the edentulous mandible from six dogs. Three implants were installed in each hemimandible, in different positions in relation to the ridge: Bone Level (at crestal bone level), Minus 1 (one millimeter ...
