BACKGROUND AND PURPOSE Previously, implant survival of total shoulder prostheses was reported to be inferior to that of hemiprostheses. However, the use of total prostheses has increased in Norway due to reported good functional results. On this background, we wanted to study implant survival of 4 major shoulder prosthesis types in Norway between 1994 and 2012. PATIENTS AND METHODS The study ...

BACKGROUND The use of Computer Assisted Surgery (CAS) for knee replacements is intended to improve the alignment of knee prostheses in order to reduce the number of revision operations. Is the cost effectiveness of computer assisted surgery influenced by patient volume and age? METHODS By employing a Markov model, we analysed the cost effectiveness of computer assisted surgery versus conventi...

After reading this article, the reader should be able to: • describe requirements that would lead to success with immediate implant placement and loading. • describe important surgical considerations to increase the survival of immediate implant restoration. • discuss advantages in the single appointment fabrication of computer-assisted designed and machined porcelain for implant restoration. •...

OBJECTIVES Short implants have become an interesting alternative to bone augmentation in dental implantology. Design of shorter implants and longer surveillance times are a current research issue. The goal of this study was to show the survival rates of short implants below 9 mm in the partly edentulous mandibular premolar and molar regions with fixed prosthetics. Marginal vertical and 2D bone ...

This study aimed to evaluate the survival rates of several external hexagon implants directly connected zirconia crowns after thermomechanical fatigue. The deformation hexagons and integrity were also evaluated. A monolithic crown (Y-TZP) four different dental (n = 10, N 40) mounted together embedded in polyurethane. specimens subjected cycling for 2.5 × 106 cycles, at 3.0 Hz frequency, 200 loa...

BACKGROUND Guided bone regeneration (GBR) has been proven to be a reliable therapy to regenerate missing bone in cases of atrophy of the alveolar crest. The aim of the present retrospective analysis was to assess peri-implant tissue conditions and document peri-implant tissue stability in C-Tech implants when placed simultaneously with a GBR augmentation procedure. METHODS A total of 47 impla...

OBJECTIVES The objectives of this systematic review were to assess the survival rate of grafts and implants placed with sinus floor elevation. MATERIAL AND METHODS An electronic search was conducted to identify studies on sinus floor elevation, with a mean follow-up time of at least 1 year after functional loading. RESULTS The search provided 839 titles. Full-text analysis was performed for...

PURPOSE The aim of this retrospective chart review was to evaluate the four-year survival rate of a titanium implant system. METHODS A total of 352 sand-blasted, thermally acid-etched titanium implants were inserted into 181 partially or completely edentulous patients. Their cumulative survival rate was evaluated retrospectively. Associated factors, such as the implant distribution and treatm...
