Prevalence and risk of peri-implant diseases based on the type of prosthetic restoration: A retrospective study after 17 to 23 years.

Statement Of Problem: Information on the epidemiology and etiopathology of peri-implant diseases in reference to prostheses is sparse.

Purpose: The purpose of this retrospective clinical study was to analyze the prevalence and risk of peri-implant diseases based on the type of prosthesis.

Material And Methods: A total of 274 implants in 106 patients were evaluated by clinical and radiological examination.

Crestal bone loss and implant failure of prefabricated versus customized abutments: a 10-year retrospective radiological study.

Objectives: There is no information today about the impact of abutment type on the crestal bone stability. This retrospective study was aimed to evaluate the crestal bone levels (CBL) and failures of implants with prefabricated and customized abutments after the long term.

Materials And Methods: The mesial and distal CBL around dental implants with prefabricated and custom abutments were recorded.

Incidence and prevalence of peri-implantitis and peri-implant mucositis 17 to 23 (18.9) years postimplant placement.

Purpose: To evaluate the prevalence of peri-implantitis (PI) and peri-implant mucositis (PM) in a long-term follow-up with comparison among different PI and PM definitions, and to report on the incidence of PI.

Materials And Methods: In a retrospective clinical study five different PI and PM definitions were applied onto a population with 274 implants 17 to 23 years postimplant placement. Recommendations by the Eighth European Workshop on Periodontology (EWOP) were used as base reference.

All-ceramic versus titanium-based implant supported restorations: Preliminary 12-months results from a randomized controlled trial.

Purpose: The aim of the present randomized controlled study was to compare prefabricated all-ceramic, anatomically shaped healing abutments followed by all-ceramic abutments and all-ceramic crowns and prefabricated standard-shaped (round-diameter) titanium healing abutments followed by final titanium abutments restored with porcelain-fused-to-metal (PFM) implant crowns in the premolar and molar regions.

Materials And Methods: Forty-two patients received single implants restored either by all-ceramic restorations (test group, healing abutment, final abutment, and crown all made of zirconia) or conventional titanium-based restorations. Immediately after prosthetic incorporation and after 12 months of loading, implant survival, technical complications, bone loss, sulcus fluid flow rate (SFFR) as well as plaque index (PI) and implant stability (Periotest) were analyzed clinically and radiologically.

Prefabricated taper crowns for the retention of implant superstructures: Three-year results of a prospective clinical trial.

Statement Of Problem: Nonrigid retainer systems for removable implant superstructures are associated with negative effects such as rocking and increased load on the denture base. Rigid retainer systems such as telescopic crowns reduce these negative effects, but their fabrication demands highly skilled dental technicians and is therefore expensive. Whether a protocol with prefabricated retainers will reduce production time is unclear.
