PURPOSE Bone density at implant placement site is a key factor to obtain the primary stability of the fixture, which, in turn, is a prognostic factor for osseointegration and long-term success of an implant supported rehabilitation. Recently, an implant motor with a bone density measurement probe has been introduced. The aim of the present study was to test the objectiveness of the bone densiti...

OBJECTIVES The purpose of the present study was to explore the maxillary sinus anatomy, its variations and volume in patients with a need for maxillary implant placement. MATERIAL AND METHODS Maxillary sinus data of 101 consecutive patients who underwent spiral computed tomography (CT) scans for preoperative implant planning in the maxilla at the Department of Periodontology, University Hospi...

Introduction: Bolton ratio is considered as seventh key of normal occlusion. Many orthodontic patients have to undergo premolar extractions as a part of treatment. Aims and objectives: The present study was taken up to investigate the effect of premolar extractions on Bolton’s overall ratios in a sample of north Indian population. Materials and methods: Mesiodistal tooth widths were measured on...

PURPOSE This prospective study followed 61 patients who were partially dentulous and considered to have insufficient bone volume for routine implant treatment and consequently underwent sinus inlay bone grafting. PATIENTS AND METHODS The patients were treated with maxillary sinus floor augmentation with particulated autogenous bone from the mandibular ramus/corpus. After a healing period, den...

This case report highlights the treatment of a skeletal Class II malocclusion with pseudoanodontia that indicated clinical but not radiographic absence of teeth. A 21-year-old female patient presented with a skeletal Class II malocclusion with an orthognathic maxilla and a retrognathic mandible, with Angle’s Class I malocclusion with rotated maxillary and mandibular anteriors with fourteen impa...

Horizontal root fractures of the posterior teeth are rare and occur due to severe trauma. We report herein a case of horizontal root fracture in the middle third of a two-rooted maxillary left first premolar. Since the coronal part of tooth was non-vital, calcium hydroxide was used as an intracanal medication for 10 days. Later, root canal therapy was successfully performed with mineral trioxid...

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...

Identifying and accessing all pulp canals is particularly challenging in the endodontic treatment of teeth with atypical canal configurations. This report describes the nonsurgical endodontic treatment of a maxillary first premolar with three root canals. The prevalence of this unusual morphology is reviewed and suggestions are offered to help dentists identify and treat such teeth. This case r...

In the Bodmin Tors example above, notice from Figure 14a (p.20) that the clustering structure is actually quite different from that of the Redwood Seedling example in 12a (p.12). Rather than small isolate clumps, there appear to be two large groups of points in the northwest and southwest, separated by a large empty region. Moreover, the points within each group are actually quite uniform with ...
