To evaluate the sealing capability of external hexagon implant systems and assess the marginal fit, two groups (n = 10 each) were employed: SIN (Sistema de Implantes Nacional, Brazil) and Osseotite, (Biomet 3i, USA). Sealing capability was determined by placing 0.7 μL of 1% acid-red solution in the implant wells before the torque of their respective abutments. Specimens were then placed into 2....

BACKGROUND Baseplate micromotion of the reverse shoulder glenoid component can lead to implant loosening. We hypothesized that a remotely positioned displacement gage measures elastic deformation of the system rather than actual micromotion at the implant/bone interface. METHODS Reverse glenoid components were implanted into polyurethane blocks of 3 different densities. A 700 N compressive lo...

BACKGROUND Accumulating evidence suggests that alveolar crestal bone resorption occurs as a result of the microgap that is present between the implant-abutment interface in dental implants. The objective of this longitudinal radiographic study was to determine whether the size of the interface or the microgap between the implant and abutment influences the amount of crestal bone loss in unloade...

OBJECTIVES The purpose of this study was to determine the influence of platform switching on stress distribution of two different implant systems using three-dimensional (3D) finite element models. MATERIALS AND METHODS Six 3D finite element models were created to replicate two different implant systems with peri-implant bone tissue, in which six different implant-abutment configurations were...

Implant rehabilitation is a daily practice in dentistry, and patients often have heightened expectations regarding both the functional aesthetic outcome. Implant–abutment connection (IAC) involved long-term quality of rehabilitation. The use one-piece implants for fixing dentures may prevent mechanical biological implication implant–abutment interface, resulting better hard soft tissue maintena...

Purpose: The aim of this study was to evaluate the surface chemistry and the microhardness at the implant-bone interface using a recently developed collagen-coated titanium implant in a short-term rabbit model. Materials and Methods: Surface chemistry was evaluated by x-ray photoelectron spectroscopy (XPS), while in vivo studies involved 4-week implants mid-diaphysis in the lateral femurs of ad...

Osseointegration refers to the direct bonding between titanium implants and bone, making it one of the key factors for the success of reconstructive and regenerative orthopaedic and dental surgeries [1]. Resolving the implantbone interface with high chemical or spatial resolution enables a clearer determination of bone growth mechanisms at the implant interface and optimal modification of impl...

Revisionary breast surgeries are challenging, and advanced techniques must often be utilized in the correction of the underlying anatomical deformities. In this Featured Operative Technique, the authors describe their method, which includes a combination of revisionary surgery techniques with site change and acellular dermal matrices. This use of acellular dermal matrices has four indications b...
