With the progressively increasing demand for orthopedic Ti implants, the balance realization between two primary complications restricting implants applications is imperative needed to be solved that the lack of bone tissue integration and biomedical device-associated infections (BAI), where emergence of multi-resistance bacteria make it worse. Notably, a combination of silver nanoparticles (AgNPs) and a kind of antibiotic can synergistically inhibit bacterial growth, where low concentration of AgNPs has been confirmed to promote the proliferation and osteogenesis of osteoblasts...

Currently, immediate loading of dental implants is very attractive as a standard protocol for prosthetic restorations in edentulous patients. The aim of this study is to find out the intimate peri-implant mucosa response depending on timing of implant loading, immediate or delayed. Fifty-one screw implants Alpha Bio (Alpha-Bio Tec, Israel) were inserted in 42 partially edentulous patients according to standardized surgical techniques. At six months of loading, samples of peri-implant mucosa were harvested from 27 immediate loaded, respectively 24 delayed loaded implants, and subjected to microscopic examination...

Incontinentia pigmenti (IP) is a uncommon gene disorder, heritage with X-linked dominant mode. IP patients have a characteristic dentition varying from marked hypodontia to delayed eruption and conical crowns on both dentitions. A 5½-year-old girl, whose mother and younger sister were also diagnosed with IP, has the whirling-like pigmented skin lesion over her trunk and four extremities. Four primary teeth and multiple permanent tooth germs were found to be congenital missing. Dental considerations of further treatment were discussed with her parents including the preservation of primary molars, possible interim prosthesis in mixed or permanent dentition, full mouth rehabilitation with orthodontic and prosthodontic combined treatment, and implant therapy in adulthood...

Ernesto A Lee
As the use of dental implants has become more common, so has the frequency of complications and unforeseen outcomes. This article describes the treatment of a complex iatrogenic defect secondary to a failed implant (No. 7) and multiple bone-grafting attempts in the maxillary anterior region. The patient's revealing smile line and high-risk circumstances demanded the use of an interdisciplinary treatment approach with high potential for predictable esthetic results. Forced eruption was performed to restore the alveolar height deficit and develop the compromised hard and soft tissues around teeth Nos...

PURPOSE: Masticatory load and efficiency vary from one individual to other. Maximum load of one person may be the least load of another. Hence, optimization of dental implants based on the load dissipation of an individual is essential for a better prognosis of implant-supported prosthesis. The aim of the study was to find the appropriate implant dimensions for the particular region based on the masticatory efficiency of the individual. MATERIALS AND METHODS: A two-dimensional-threaded implant model was designed, which was duplicated in total 28 models with varying dimensions starting from 3 mm × 8 mm till 6 mm × 14 mm, with an incremental increase of 2 mm in length and 0...

REVIEW
Dennis Flanagan
Dental implants are placed endosseously, and the bone is the ultimate bearer of the occlusal load. Patients are not uniform in the maximum bite force they can generate. The occlusal biting load in the posterior jaw is usually about three times of that found in the anterior. It is possible for supporting implants to be overloaded by the patients' biting force, resulting in bone loss and failure of the fixture. Bite force measurement may be an important parameter when planning dental implant treatment. Some patients can generate extreme biting loads that may cause a luxation of the fixture and subsequent loss of osseointegration...

STATEMENT OF PROBLEM: Implant prosthodontics provides high-quality outcomes thanks to recent technological developments and certification procedures such as International Organization for Standardization (ISO) standard 14801. However, these certification tests are costly, and the result is highly uncertain as the influence of design variables (materials and structure) is still unknown. The design process could be significantly improved if the influence of design parameters were identified...

Titanium and its alloys are widely employed materials for implants in orthopedic or dental surgery due to their mechanical properties, resistance to corrosion and osseointegration capability. However adverse reactions at the tissue/implant interface may occur, which limit the success of the osseointegration process. Therefore, different strategies have to be used to overcome these drawbacks. In this work, we developed two different liposome-based coatings on titanium surfaces as drug or bioactive molecule deposits for dental/orthopedic implant applications...

BACKGROUND: The sinus lift (or sinus augmentation) is a common procedure to improve maxillary bone stock before dental implantation. Chronic rhinosinusitis (CRS) is a potential complication of this procedure and may be refractory to medical treatment. Functional endoscopic sinus surgery has previously been used to address CRS, however, results of previous studies indicated that implant removal is required. There are limited follow-up data available. OBJECTIVE: The purpose of this study was to characterize the long-term outcomes and efficacy of endoscopic sinus surgery for refractory CRS after sinus lift, including the ability to salvage dental implants...
