Background and Aim: Medical grade calcium sulfate hemihydrate (MGCSH) is used as a bone graft material for socket preservation. This study aimed to evaluate the changes in bone width and height after tooth extraction and socket preservation with MGCSH using cone-beam computed tomography (CBCT). Materials and Methods: This study evaluated 17 systemically healthy patients over a 1-year period. Th...

Dentistry has entered an era in which patients no longer need to accept an edentulous or partially edentulous condition, or one in which their candidacy for tooth structure replacement (ie, implants with subsequent restoration) must be dismissed because of insufficient alveolar bone volume, height, or width. The supporting bone can be preserved at the time of tooth extraction, or augmented at t...

Objectives: To study the biometric dimensions of upper front teeth in a Hong Kong SAR population including gender differences and compare this with often recommended use Golden Proportion when selecting tooth proportions. Methods: A sample dental casts was obtained from 100 patients: 50 females males an age range 18 to 35 years. The selected based on criteria intact maxillary anterior arches, f...

The crown-root fracture is a common tooth injury which compromises the biological width and need proper endodontic and prosthodontic treatment to achieve acceptable clinical outcome. This case report describes clinical management of crown-root fracture in maxillary central incisors which was successfully treated by forceps eruption with 180 ̊ rotation to restore the biological width. The patient...

Figure 2. Extrusion after 1 week. A subgingivally fractured incisor presents a restorative challenge. Orthodontic eruption is a good alternative to crown lengthening for restoring the biological width, maintaining the alveolar bone, and restoring esthetics. The technique requires a hook to serve as the attachment system, fixed to the fractured tooth root, and an anchorage bar to allow movement ...

AIM To report the successful and conservative management of a fractured immature permanent maxillary incisor tooth with talon cusp by fracture reattachment. SUMMARY Coronal fractures of the maxillary anterior teeth are common dental injuries. Among these, the complicated fractures especially in immature teeth require an unambiguous treatment without any delay. When the tooth fragment is avail...

AIMS To establish the minimum dimensions for a non-precious cast metal occlusal rest by using mathematical analysis. An occlusal rest in a removable partial denture (RPD) provides vertical support and allows occlusal forces to be transmitted through the long axis of the abutment tooth. METHODS The stress status of an occlusal rest in a posterior tooth-bounded RPD resembles that of a cantileve...
