Short dental implant

Yingdi Yan, Emil Chibowski, Aleksandra Szcześ
Titanium (Ti) and its alloys are the most often used implants material in dental treatment and orthopedics. Topography and wettability of its surface play important role in film formation, protein adhesion, following osseointegration and even duration of inserted implant. In this paper, we prepared Ti-6Al-4V alloy samples using different smoothing and polishing materials as well the air plasma treatment, on which contact angles of water, formamide and diiodomethane were measured. Then the apparent surface free energy was calculated using four different approaches (CAH, LWAB, O-W and Neumann's Equation of State)...

In oral implantology, the most serious complications occur intraoperatively or within a short period. We describe an unusual case of focal osteoporotic bone marrow defect involving dental implant in the posterior mandibular region of the adult woman. Despite the fact that this condition requires no treatment, it could lead to the displacement of the dental implant. Additionally, this case report reinforces that histopathological analysis is mandatory for precise diagnosis of the radiolucency into posterior mandibular region of the adult woman associated or not with dental implant placement...

In oral rehabilitation, crown-to-root ratio is accepted as an indicator of bone loss, and this concept was transferred to implants. Recent studies have indicated that there is no significant difference between short and standard implants. The aim of this study was to compare marginal bone-level alteration through radiographic evaluation and clinical parameters between short and standard implants supporting single crowns. This prospective clinical trial study included 82 systemically healthy, nonsmoking subjects...

Short dental implants have been used as an attempt to avoid bone grafts surgery, however there are few literature reports that evaluate changes to their design. Therefore, the aim of this study was to assess the effect of different short implant design on stress distribution through photoelastic analysis. Six external hexagon (5 × 5 mm) short dental implants with different design were used. Each group was treated with a single crown and a three element fixed partial dental prosthesis, resulting in a total of 12 photoelastic models...

We evaluated two treatment concepts for the rehabilitation of moderate atrophic maxilla with dental implants (all-on-four and all-on-six) and the effect of framework material on the stress distribution of implant-support system. A three-dimensional finite element model based on a prototype was built to simulate an entirely edentulous maxilla with moderate sinus pneumatization that was rehabilitated with a full-arch fixed dental prosthesis. Four standard implants were positioned according to the all-on-four concept and four standard implants and two short implants were placed according to the all-on-six concept...

This study focuses on the fatigue behavior and bone-implant attachment for the more usual surfaces of the different cp-titanium dental implants. The implants studied were: as-received (CTR), acid etching (AE), spark-anodization (SA) and with a grit-blasted surface (GB). Residual stresses were determined by means of X-ray diffraction. The fatigue tests were carried out at 37°C on 160 dental implants and the S-N curve was determined. The fatigue tests show that the grit-blasting process improves the fatigue life...

Although highly successful in terms of both short- and long-term survival rates, All-on-4®-style dental implant treatment is a multistep process with many potential complications. Beyond reports of survival rates for dental implants and the final prostheses, the dental literature is relatively devoid of information regarding obstacles and pitfalls associated with All-on-4-style dental implant treatment. In the current article, the author describes common issues that he has encountered before, during, and after All-on-4-style dental implant treatment of more than 500 arches and discusses methods for overcoming these obstacles...

OBJECTIVE: In this study, we compared the success of sinus lifting and alternative treatment methods in applying dental implants in cases lacking adequate bone due to pneumatization of the maxillary sinus. METHODS: In a computer environment, 3D models were created using computerized tomography data from a patient. Additionally, implants and abutments were scanned at the macroscopic level, and the resulting images were transferred to the 3D models. Five different models were examined: a control model, lateral sinus lifting (LSL), short dental implant placement (SIP), tilted implant placement (TIP) and distal prosthetic cantilever (DC) use...
