After exposing a submerged implant to the oral environment, bone loss occurs downwards along the implant body and stops at some predefined position. A current area of hot debate is the significance of the implant abutment interface and its influence on crestal bone level in relation to the first thread. In recent years, the microgap which exists at the connection between the implant body and th...

Following extraction of the teeth, the remaining socket heals from the apex toward the crest. When nothing is placed into the socket at the time of tooth removal, the infiltration of soft tissue at the crest often results in facial and crestal bone loss. Many literatures consider socket preservation as a necessity for further esthetic considerations in the pre-prosthetic and corrective procedur...

A slowly enlarging gingival mass with a reddish-purple surface is observed in a school-age boy. The lesion was first noted 3 months ago during a routine oral examination but recently it has increased in size and interferes with eating. A periapical radiograph demonstrated focal loss of the alveolar crestal bone in the mandibular incisor region. The diagnosis of peripheral giant cell granuloma, ...

Aim: the aim of present study was Evaluate clinical outcome residual subgingival cement in Prosthetic Dentures Reliant on Dental Implants. Method: Databases PubMed, Scopus, Web Science, EBSCO and Embase were searched for systematic literature until March 2022. 95% confidence interval effect size with fixed model Inverse-variance method calculated. Meta-analysis performed using Stata/MP v.16 sof...

PURPOSE To clinically evaluate immediate implant placement with simultaneous intentional retention of the buccal aspect of the root and to report longitudinal data on survival of implants placed with the use of this novel technique. MATERIALS AND METHODS A retrospective case series of implants placed with the root-membrane technique in the maxillary anterior region of adult patients was condu...

Purpose: The purpose of this study was to measure marginal bone loss from the implant-abutment microgap to the bone crest between multiple freestanding implants functionally loaded for up to 7.5 years in the posterior jaws. Materials and Methods: Patients consecutively treated for the replacement of missing posterior teeth were included in the study. Using the implant-abutment interface, which ...

PURPOSE The aim of the study was to analyze the amount of maxillary and mandibular crestal bone loss around Bredent Sky Blue type of implants of different dimensions one year after implantation. MATERIALS AND METHODS 36 implants of diameter 3.5 x 10 mm were inserted in the maxilla and 12 in the mandible. 52 implants of diameter 4.0 x 8 mm were inserted in the maxilla, and 61 in the mandible (...

In 61 patients, 61 consecutive implants were placed immediately after extraction of one anterior or premolar maxillary tooth. One of 3 surgical approaches based on rotated full (RPF) or rotated split (RSPF) palatal flaps, with and without the use of barrier membranes to enable primary soft tissue closure, was applied. A bovine bone mineral graft was used in all cases. At the time of implant pla...

BACKGROUND The hypothesis of bacterial infection initiating marginal bone loss around dental implant in analogy with natural tooth is still in debate. PURPOSE The aim of this retrospective study was to investigate the effects of uncontrolled periodontitis on marginal bone alterations around implants compared with the periodontal health group at a mean follow-up of at least 6 years.
