PURPOSE The aim of this study was to analyze the short-term predictability and reliability of Astra Tech implants according to the demographical distribution of patients and condition of implant sites and location of implants. METHODS Among patients treated with Astra Tech implant (Astra Tech AB) in the Department of Periodontology at the Dental Hospital of Yonsei University of College of Den...

PURPOSE The aim of this clinical trial was to evaluate the influence of gingival tissue thickness on crestal bone loss around dental implants after a 1-year follow-up. MATERIALS AND METHODS Forty-six implants (23 test and 23 control) were placed in 19 patients. The test implants were placed about 2 mm supracrestally, whereas the control implants were positioned at the bone level. Before impla...

The successful use of surgical and medical methods jaw bone tissue restoration has been convincingly confirmed in clinical practice. At the same time, technologies are being developed to improve osseointegration dental implants patients with osteoporosis. various implant coatings, as well systemic therapy, demonstrate emergence new directions treatment partial or complete secondary edentulism c...

OBJECTIVES The primary objective of this open, retrospective, nonrandomized study was to evaluate survival and success rates for sandblasted, large-grit, acid-etched (SLA) and titanium plasma-sprayed (TPS) implants placed by a single practitioner. The secondary objectives included evaluation of crestal bone loss and adverse events. MATERIALS AND METHODS Implants were placed by a single practi...

Implant placement in the posterior regions can be limited due to anatomical conditions. One of the most problematic areas is the posterior maxilla, presenting in most cases with a limited bone height due to the pneumatisation of the maxillary sinus, and poor bone quality. Another complicating factor in posterior regions is the general exposure to greater masticatory loads than in anterior regio...

Since the alveolar process is tissue "dental dependent," after the extraction of the dental element, this process suffers some degree of atrophy during the healing process, which can be reduced with the installation of immediate implants, aiming to maintain the original bone architecture. The aim of this study was to investigate the influence of the time of implant placement on bone formation a...

Additive manufacturing (AM) allows for the fabrication of custom orthopaedic implant devices which have complex geometries and similar mechanical properties to bone. This paper reviews corrosion, fatigue wear AM Ti alloys confirm their safety use in implants. Specifically, lattice are highlighted due improved osseointegration better modulus matching with that bone, making them an attractive opt...

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 ...

BACKGROUND Numerous studies have shown the superiority of platform-switched implants in preserving crestal bone as compared with platform-matched implants. However, the influence of initial soft tissue thickness on development of crestal bone loss has not been addressed in previous studies; thus, further research is needed. PURPOSE To evaluate crestal bone levels around platform-switched impl...
