Bicortical dental implantation technique was regarded as an alternative to internal sinus lift technique with bone grafting in dental implantation in atrophic maxillae. The purpose of this retrospective study was to evaluate the survival rates and bone stability of 6- and 10-mm implants in the posterior maxilla using bicortical dental implantation techniques after 1 to 5 years of prosthetic loading. A total of 53 patients received posterior maxillary implant treatments. Of these, 31 patients received bicortical dental implantation (group A), and 25 patients received traditional implantation (group B)...

OBJECTIVES: During the physiological ageing process atrophy of the alveolar bone appears in vertical direction. This bone resorption causes pushing the limits of the maxillary sinus at the expense of a degraded bone. The sinus volume increases due to the facial development in children and adolescents or during the ageing process due to the loss of teeth and bone mass. The main aim of this study is to determine the sinus shape and sinus floor morphology related to age. MATERIALS AND METHODS: Human adult male and female cadaveric heads (aged 37 to 83 years) with different dental status were used...

This case describes the successful long-term outcome of a patient's treatment after a restorative failure occurred soon after delivery. The esthetic and restorative treatment has been successful for nearly a decade due largely to a careful, objective evaluation of all possible causes of the restorative failure. The treatment plan for the patient, who was assessed as high risk biomechanically and functionally, was carried out in the following phases: (1) an implant placement that required an osteotome sinus lift; (2) placement of feldspathic bonded veneers for the maxillary anterior teeth to minimize removal of tooth structure; (3) numerous core-supported restorations, with fixed partial dentures placed for teeth Nos...

Osseointegrated implants are now commonplace in contemporary dentistry. However, a number of complications can occur around dental implants, including peri-implantitis, maxillary sinusitis, osteomyelitis, and neoplasms. There have been several reports of a malignant neoplasm occurring adjacent to a dental implant. In this report, we describe 2 such cases. One case was that of a 75-year-old man with no previous history of malignant disease who developed a solitary plasmacytoma around a dental implant in the left posterior mandible, and the other was that of a 43-year-old man who was diagnosed with squamous cell carcinoma adjacent to a dental implant in the right posterior mandible...

Sinus augmentation is a routine procedure performed in patients presenting with severe atrophy of the posterior maxillary alveolar ridge who seek dental implant surgery. Although this strategy is successful in large part, complications such as maxillary sinusitis, antral bleeding, resorption of graft material, infection, failure of implant installation, and oroantral fistula formation are documented on occasion. However, reports of postoperative maxillary cyst (POMC) arising after sinus augmentation are rare...

Background: For dental implant planning in maxillary posterior region, it is essential to know their relationship with maxillary sinus. Maxillary posterior teeth affected by chronic periodontitis usually have a poor prognosis, ultimately leading to tooth loss. Following tooth loss, significant bone resorption occurs resulting in compromised remaining bone support for dental implant placement. Aim: The study aims to determine the relationship between inferior wall of maxillary sinus and the root apices of maxillary posterior teeth...

Bone mass is important for dental implant success and is regulated by mechanoresponsive osteocytes. We aimed to investigate the relationship between the levels and orientation of tensile strain and morphology and orientation of osteocytes at different dental implant positions in the maxillary bone. Bone biopsies were retrieved from eight patients who underwent maxillary sinus-floor elevation with β-tricalcium phosphate prior to implant placement. Gap versus free-ending locations were compared using 1) a three-dimensional finite-element model of the maxilla to predict the tensile strain magnitude and direction and 2) histology and histomorphometric analyses...
