Repeated delivery of chlorhexidine chips for the treatment of peri-implantitis: A multicenter, randomized, comparative clinical trial.

Background: Peri-implantitis is a challenging condition to manage and is frequently treated using non-surgical debridement. The local delivery of antimicrobial agents has demonstrated benefit in mild to moderate cases of peri-implantitis. This study compared the safety and efficacy of chlorhexidine gluconate 2.

Effect of implant neck design on primary and secondary implant stability in the posterior maxilla: A prospective randomized controlled study.

Objective: To compare the early changes in implant stability of implants with different neck design during the first 3 months of healing in the posterior maxilla.

Materials And Methods: Patients were randomized to receive triangular neck implant (test), or round neck implant (control). Resonance frequency analysis (ISQ) measurements were obtained at surgery and at 2, 4, 7, 14, 21, 28, 45, 60, and 90 days following implant placement.

Microbial accumulation on different suture materials following oral surgery: a randomized controlled study.

Background: The aim of the study was to compare bacterial accumulation on different suture materials following oral surgery.

Methods: Patients scheduled for implant or periodontal surgery were included in the study. Upon flap closure, four different sutures were placed in a randomized sequence-silk, coated polyglactin, nylon, and polyester.

Myiasis in Travelers.

Background: Cutaneous myiasis is a well-established diagnosis in returning travelers from tropical countries. The most common form of myiasis seen in this population is localized furuncular myiasis caused by Dermatobia hominis and Cordylobia anthropophaga. There are limited data on the disease course and outcome in travelers to tropical countries.

High rate of schistosomiasis in travelers after a brief exposure to the high-altitude Nyinambuga crater lake, Uganda.

Travel-related schistosomiasis is usually associated with prolonged freshwater exposure. Until recently, Uganda's crater lakes were considered schistosomiasis free due to their high-altitude location. We describe an outbreak of acute schistosomiasis after a brief exposure (mean, 22 ± 9.

Acute hepatitis in israeli travelers.

Background: Acute hepatitis is a well-described cause of morbidity and sporadic mortality in travelers. Data regarding the epidemiology of hepatitis in travelers are lacking. The aim of this study is to describe the epidemiology of acute viral hepatitis among travelers returning from tropical countries, with particular attention to enterically transmitted hepatitis.

A rough surface implant neck with microthreads reduces the amount of marginal bone loss: a prospective clinical study.

Objectives: An intra-individual controlled clinical trial was conducted to evaluate and compare the amount of marginal bone loss (MBL) found around implants of a comparable design, with or without retention grooves (microthreads) or polished necks, during the early stages of healing.

Materials And Methods: Forty-eight (48) patients with missing mandibular posterior teeth were treated with two commercially available implants of the same brand (MIS): one with microthreads (S-model) and the other with a polished neck (L-model). MBL around each implant was measured on follow-up radiograms taken 4 months after placement (exposure and crown cementation), and 6 and 12 months after loading.

Removable prostheses may enhance marginal bone loss around dental implants: a long-term retrospective analysis.

Background: The aim of the study was to retrospectively evaluate marginal bone loss (MBL) around rough-surface dental implants, placed in a private clinic, and to construct a multivariate model based on formerly proposed prognostic variables.

Methods: Records of patients who were treated previously with dental implants were reviewed. The patients' latest annual clinical examinations and radiograms were used for data collection and the calculation of MBL.

Teeth realignment for enhanced posterior single implant restorations.

As the use of dental implants became a widespread and acceptable treatment modality, with an overall good long-term prognosis, treatment concepts changed reciprocally. Nowadays, dental implants are considered routine and are preferred over other modalities such as removable or fixed partial dentures or etched cast restorations supported by neighboring teeth. However, we often find clinical situations that challenge the placement of an implant because of insufficient space.
