The reconstruction of large osseous defects due to periodontitis is a challenge in regenerative therapy. Sclerostin, secreted by osteocytes, is a key physiological inhibitor of osteogenesis. Pharmacologic inhibition of sclerostin using sclerostin-neutralizing monoclonal antibody (Scl-Ab) thus increases bone formation, bone mass and bone strength in models of osteopenia and fracture repair. This...

it appears that until bone graft has not achieved 100% success, intraradicular diseases remain controversial and therefore, different treatment plans are suggested for them. treating intraradicular diseases depend on many factors: maxillary molars are more prone to bone loss and have worse prognosis. to assess prognosis more carefully these factors should be considered: 1) bone loss: its apical...

the palatogingival grooves are an anatomical anomaly in maxillary incisors and the presence of them may result in local periodontal pocket formation, bone loss and sometimes pulpal necrosis. in the present case, there was a groove on the palatal side of maxillary lateral incisor with vital pulp. the periodontal problem of the tooth was treated and the 6 month postoperative follow up showed atta...

AIM The purpose of this report is to provide a brief literature review of the bone-added osteotome sinus floor elevation (BAOSFE) procedure and to present a case utilizing this technique. BACKGROUND Implant placement in the posterior maxillary region is often compromised due to anatomic limitations. In clinical situations where there is inadequate vertical bone dimension, the BAOSFE technique...

J Korean Assoc Oral Maxillofac Surg 2012;38:110-5) Ankylosed tooth is defined as ‘the discontinuance of normal passive tooth eruption without any mechanical barrier’. Ankylosed tooth treatment is a challenge to dental clinicians. In treatment of maxillary molar ankylosis cases there are risks of oro-antral fistula, displacement of root fragments into the maxillary sinus, as well as the necessit...

BACKGROUND The aim of this study was to measure the distance between the maxillary premolar and molar teeth apices to the buccal cortical bone and evaluate differences in gender and age group, using cone beam computed tomography (CBCT). MATERIAL AND METHODS This retrospective study comprised of 451 premolar and molar teeth of one hundred and thirteen patients who were admitted to Dicle Universi...

OBJECTIVES The aim of this study was to retrospectively evaluate the clinical survival rate of Astra Tech implants in the maxillary molar region performed with sinus lift and bone graft. MATERIALS AND METHODS Ninety-nine Astra Tech implants (Osseospeed) placed in the maxillary molar region using sinus lift from September 2009 to February 2012 were selected with a minimum follow-up period of 1...

Background and aims. All-on-four technique involves the use of tilted implants to allow for shorter cantilevers. This finite element analysis aimed at investigating the amount and distribution of stress in maxillary bone surrounding the implants with all-on-four vs. frequently used method with six implants technique using different numbers and inclination angles. Materials and methods. A 3D ede...

PURPOSE To evaluate bone healing in the extraction socket of the feline maxillary canine tooth after grafting. METHODS Eighteen adult cats were submitted to unilateral extraction of maxillary canine tooth and divided into three groups. In group 1 (n=6), control, the extraction socket was left empty. In group 2 (n=6), the extraction socket was filled with autogenous cancellous bone from the il...

PURPOSE The maxillary sinus lift is recognized and stable, and there have been different innovations to optimize the technique. The aim of this study was to investigate the maxillary sinus lift technique with the use of a blood clot and without the use of a bone graft. MATERIALS AND METHODS Ten patients were recruited for a unilateral sinus lift; patients without sinus pathology or other cont...
