INTRODUCTION A study is made of the usefulness of cytokines (such as interleukin-6 (IL-6), interleukin-8 (IL-8), interleukin-10 (IL-10) and interleukin-12 (IL-12)) as markers of periimplant disease (mucositis and periimplantitis). An increase in the levels of these cytokines in dental implant crevicular fluid may give rise to a lack of osteointegration, bone loss or implant failure. OBJECTIVE...

BACKGROUND The objective of this study was to investigate the stress distribution in the bone around zygomatic and dental implants for 3 different implant-retained obturator prostheses designs in a Aramany class IV maxillary defect using 3-dimensional finite element analysis (FEA). MATERIAL AND METHODS A 3-dimensional finite element model of an Aramany class IV defect was created. Three diffe...

This paper presents three cases of peri-implant mucosal defects that were successfully treated with a newly proposed "pouch roll" implant soft tissue augmentation technique. This procedure uses a de-epithelialized connective tissue layer during the first or second stage of implant surgery over the underlying dental implant without the need for sutures. At 2 weeks, healing was remarkable, with e...

BACKGROUND Alendronate sodium increases alveolar bone density with systemic use. It inhibits osteoclast activity and is thought to result in a net increase in osteoblastic activity. However, little is known about local in vivo use. The purpose of this study was to evaluate the effect of local delivery of alendronate on bone regeneration within peri-implant defects. Peri-implant bone was examine...

CT-based dental imaging for implant planning and surgical guidance carries both clinical and radiographic information for implant positioning as far as trajectory, depth and distribution. The significance of accurate planning and surgical guidance as it pertains to critical anatomical landmarks, such as the mandibular canal, maxillary sinus and adjacent teeth, cannot be overstated. This case re...

CAD/CAM (Computer-aided design/Computer-aided manufacturing) dental implant surgical templates applied in the immediate implant surgery in esthetic area,is beneficial to acquire appropriate three-dimensional position,realize the transformation that from virtual plan to practical surgery, from traditional surgery depended on experience to digital and accurate surgery, improve predictability, acc...

BACKGROUND The existing information on oral rehabilitations with dental implants in VIH-positive patients is scarce and of poor quality. Moreover, no long-term follow-up studies are available. Hence, the aims of this study were to describe the long-term survival and success rates of dental implants in a group of HIV-positive patients and to identify the most common postoperative complications, ...

The aim of this study is to evaluate the performance of implant-derived minimally invasive sinus floor elevation. A multicenter retrospective study was performed in 5 dental clinics. Patients requiring sinus augmentation for single implant placement were recorded and followed up. The dental implant used in this trial was a self-tapping endosseous dental implant that contains an internal channel...
