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 ...

AIM This study sought to investigate dimensional changes to the alveolar bone following extraction and application of novel devices used for obturation of socket orifice (socket cap) and space maintenance in sockets with facial dehiscence (socket cage). MATERIAL AND METHODS Six Macaca fascicularis had six teeth each removed according to the following intervention groups (groups A-C intact alv...

OBJECTIVES To address the following focused question: What is the impact of implant-abutment configuration and the positioning of the machined collar/microgap on crestal bone level changes? MATERIAL AND METHODS Electronic databases of the PubMed and the Web of Knowledge were searched for animal and human studies reporting on histological/radiological crestal bone level changes (CBL) at nonsub...

PURPOSE Studies of maxillary overdentures supported by endosseous implants often show a high implant failure rate. The aim of the present investigation was to evaluate clinically and radiographically non-submerged implants supporting an overdenture in the maxilla. MATERIALS AND METHODS Forty-one patients were consecutively admitted for treatment. The standard procedure was to place 4 implants...

OBJECTIVES If teeth are missing, super-eruption of teeth in the opposing arch can occur in the area and can change the occlusal plane. When missing teeth are replaced with implants, the oral surgeon must determine whether or not the super-erupted teeth need to be treated in order to normalize the occlusal plane. In this study, we evaluated the clinical prognosis of dentition after implant place...

Methods: Light-hardened poly-methyl-methacrylate, poly-hydroxyl-ethyl-methacrylate, and calcium hydroxide plus polyanhydride (PPCH+PA) composite graft), PPCH graft alone, PA graft alone, were compared to each other and to a no graft control group. All mandibular premolar teeth were extracted; a total of 48 implants were placed into sockets of the mesial roots in three minipigs. Crestal areas an...

Over the last years, growing attention has been paid to the several domestic implant systems. This study presents results of a clinical trial of Implantium® implants followed up to 22 months. Two hundred fifty-two Implantium® implants were investigated which were placed in 119 patients between June 2003 and November 2004. The average follow-up period from implant placement was 10. 9months(SD 4....

The conventional placement protocol for submerged and non-submerged implants was proposed in the 1960s and 1970s. Multicenter studies have reported satisfactory success rates for both protocols and a similar loss of crestal peri-implant bone after implant loading (0.5 to 1.5 mm). In recent years, placement of submerged implants using a single surgical procedure was introduced, with the immediat...

The objective of this study was to compare the alveolar bone growth in the 2 sides of the maxillary sinus after bilateral sinus lift procedures were performed with the simultaneous placement of dental implants in 20 consecutive patients. After elevation of the Schneiderian membrane, one side had only platelet-rich plasma (PRP) gel applied, while the other had placed only alloplastic graft mater...

OBJECTIVES The aim of this consensus meeting was to assess the impact of implant-abutment connection, positioning of the machined collar/microgap, and platform switching on crestal bone level changes. MATERIALS AND METHODS Two comprehensive systematic reviews were prepared in advance of the meeting. Consensus statements, practical recommendations, and implications for future research were bas...
