PURPOSE The purpose of this study was to record the effectiveness of Gold-Tite square abutment screws, tightened to 35 Ncm with a torque indicator, in maintaining a clinically stable implant/abutment connection. MATERIALS AND METHODS The study consisted of 73 patients who were treated with 110 Osseotite implants. All patients were restored with either pre-machined titanium or customized UCLA ...

PURPOSE The aim of this study was to review the published literature investigating the accuracy of fit of fixed implant frameworks fabricated using different materials and methods. MATERIALS AND METHODS A comprehensive electronic search was performed through PubMed (MEDLINE) using Boolean operators to combine key words. The search was limited to articles written in English and published throu...

The accuracy of 12 impression materials of six different types were studied by using complete-arch FPD impressions. Sixty impressions were made of a Columbia dentoform maxillary model with complete cast crown abutment preparations on the canines and the second molars. A one-piece casting was constructed by connecting the four individual castings made for the four abutment teeth. The master pros...

Materials and Methods: Patients for the prospective long-term case cohort study were recruited for a complete clinical and radiographic examination at 1 and 10 year intervals after implant placement. The sample size of this study was 89 patients with an age range of 28-88 years. The treatment plans for implant restoration utilized 3 restorative treatment plans: single crowns (SC); implant-impla...

PURPOSE The purpose of this study was to use a clinical simulation to determine whether wear of the internal surface of a titanium implant was greater following connection and loading of a one-piece zirconia implant abutment or a titanium implant abutment. MATERIALS AND METHODS Two implants received zirconia abutments and two received titanium abutments. The implants were secured into four fi...

Objective To evaluate the influence of artificial aging on transformation propagation and fracture resistance zirconia implants. Methods One-piece (with integrated implant abutment, 1P; regular diameter [4.1mm]; n = 16) two-piece separate 2P; wide [5 mm]; implants were embedded according to ISO 14801. A titanium–zirconium (Ti-Zr; 4.1 mm diameter) served as a control (n 16). One subgroup 8) each...
