OBJECTIVES The aim of this study was to examine the effect of basic fibroblast growth factor (FGF-2) on osseointegration of dental implants with low primary stability in a beagle dog model. MATERIALS AND METHODS Customized titanium implants that were designed to have low contact with the existing bone were installed into the edentulous mandible of beagle dogs. To degrade the primary stability...

Purpose: The long-term success of an implant depends on the stability of bone support for the implant. Most crestal bone loss occurs in the first year of implant placement. Platform-switching is an approach which can be clinically applied to preserve the crestal bone. The concept of ‘platform switching’ refers to the use of a smaller-diameter abutment on a larger-diameter implant collar. The pu...

Short stemmed hip endoprostheses represent a relevant alternative to standard sized total hip stems. Especially in terms of bone stock preservation and minimal invasiveness the reduced length of such implants is beneficial. However, the smaller implant size is linked to a reduced surface geometry and thereby bone-implant-interface to provide implant stability. In order to evaluate the interfaci...

Osseointegration of titanium implants is a complex biological process involving interactions between immuno-inflammatory responses, angiogenesis and osteogenesis, all of which are influenced by the physical and chemical characteristics of the implant surface. An implant surface with moderately rough topography and high surface energy influences cellular activities, enhancing peri-implant bone w...

OBJECTIVES Implant placement in molar extraction sockets can be difficult due to complex multi-root anatomy and the lack of predictable primary stability. The aim of this study was to evaluate the outcome of an 8 - 9 mm diameter tapered implant, designed to be placed in molar extraction sockets. MATERIAL AND METHODS Patients treated at least 1 year before with a Max(®) implant (Southern Impla...

PKIP Description • Newly developed patient-reported outcome (PRO) measure • Assesses knee implant functional performance • For use with patients before and after primary total knee arthroplasty (TKA) • Assesses factors that lead to patient dissatisfaction and describes unmet needs in knee functional performance • Addresses stability, motion, satisfaction, and confidence with knee implant • 24 i...

General term of implantation implies insertion of biomaterials of different designs into the tissues. Oral implantation is a surgical insertion of aloplastic materials (metals, alloys, ceramics, polymers, carbons as well as their combinations) into the hard and soft tissues of the upper and lower jaws . The essence of implantology lies in favorable reaction of the organism to the presence of fo...

ABSTRACT In order to evaluate the effect of countersinking on dental implants primary stability installed in low density bones, thirty dental implants were installed in the most proximal region of oxen ribs and grouped as follow: Group1: Fifteen implants installed by standard drilling with countersinking, Group2: Fifteen implants installed by standard drilling without countersinking. The gradua...

Prosthetic replacement in the hand must address such unique challenges as preservation of the collateral ligaments, tendon balancing, and stability. Some recently developed implant arthroplasties of the metacarpophalangeal and proximal interphalangeal joints have anatomically designed articular components; others have non-cemented, press-fit, carefully contoured intramedullary stems. The ration...

The primary stability of cementless total hip endoprosthesis is of vital importance for proximate, long-term osteointegration. The extent of micromotions between implant and acetabulum is an indicator of primary stability. Based on this hypothesis, different cementless hip joint endoprosthesis were studied with regard to their micromotions. The primary stability of nine different cementless thr...
