the maxillofacial region is one of the most injury-prone areas during road traffic accidents, personal violence, falls and sports. maxillofacial trauma can lead to breakage or avulsion of upper anterior teeth, which may cause significant aesthetic and functional problems. there are many treatment options available for rehabilitation including removable partial dentures, fixed partial dentures, ...

background and aims. different clinical studies have reported high survival rates in immediate implant placement in extraction sockets with periapical lesions. the aim of this study was to investigate the effect of er:yag laser irradiation on success rate of immediate implant placement in tooth extraction sockets with chronic periapical lesions. materials and methods. thirty patients requiring ...

Soon after tooth extraction the bone resorption takes place reducing the height and width of alveolar ridge. This produces an altered morphology of the bone unfavorable for implant placement and implant placement becomes impossible without surgical correction. Socket grafting maintains and preserves ridge for implant placement.

The aim of this study was to achieve aesthetically pleasing soft tissue contours in a severely compromised tooth in the anterior region of the maxilla. For a right-maxillary central incisor with localized advanced chronic periodontitis a tooth extraction followed by reconstructive procedures and delayed implant placement was proposed and accepted by the patient. Guided bone regeneration (GBR) t...

In this prospective case series study, 20 patients with an implant-borne single crown following early implant placement with simultaneous contour augmentation were followed for 6 years. Clinical, radiologic, and esthetic parameters were assessed. In addition, cone beam computed tomography (CBCT) was used at 6 years to examine the facial bone wall. During the study period, all 20 implants were s...

The practice of immediate implant placement is gaining momentum in clinical practice and can be a very rewarding way to deliver implant therapy to patients. Appropriate patient selection and an understanding of newly developed techniques and protocols are needed to ensure that the high rates of success seen with conventional implant therapy hold true for implants placed immediately. While gaini...

PURPOSE This study was performed to evaluate the changes of jaw bone density around the dental implant after placement using computed tomography scan (CT-Scan). MATERIALS AND METHODS This retrospective study consisted of 30 patients who had lost 1 posterior tooth in maxilla or mandible and installed dental implant. The patients took CT-Scan before and after implant placement. Hounsfield Unit ...

The anterior maxilla presents a challenging milieu interior for ideal placement of implants because of the compromised bone quality. With the advent of intraoral bone harvesting and augmentation techniques, immediate implant placement into fresh extraction sockets have become more predictable. Immediate implant placement has numerous advantages compared to the delayed procedure including superi...

STATEMENT OF PROBLEM Surgical guides may interfere with effective use of surgical instrumentation during implant placement in the posterior segments where interocclusal distance may be limited. PURPOSE The purpose of this study was to measure and compare the accuracy of posterior implant placement using 3 precision surgical guides with varying occlusogingival heights, and to evaluate the diff...

OBJECTIVES The aim of this prospective study was to evaluate dimensional alterations of the peri-implant tissues at single-tooth restorations from the time of implant placement to 1-year post-loading. MATERIAL AND METHODS Eleven patients, aged 18-36 years, subjected to single-tooth replacements with implant-supported restorations (Brånemark implant system) in the maxillary anterior region wer...
