A comparative study of the cutting efficiency of diamond rotary instruments with different grit sizes with a low-speed electric handpiece against zirconia specimens.

Statement Of Problem: The use of zirconia in dentistry has increased. However, little attention has been given to the difficulty experienced by clinicians when cutting zirconia restorations intraorally. Evidence for which grit size and type of rotary instrument is best for cutting zirconia intraorally is lacking.

Comparison of excess cement around implant crown margins by using 3 extraoral cementation techniques.

Statement Of Problem: Extrusion of excess cement into the subgingival area around implant-supported crowns is associated with detrimental inflammatory response, but controlling this excess material remains a challenge.

Purpose: The purpose of this in vitro study was to perform a comparative analysis of 3 extraoral cementation techniques to reduce excess extruded cementation material around implant-supported crowns.

Material And Methods: Forty-four internal connection implant replicas were embedded in acrylic resin to form the experimental model.

Immediate Implant Placement and Provisionalization Following Tumor-Resective Surgery in the Midfacial Region: A Case Series.

Surgical and prosthodontic restoration of the midfacial region following tumor resection has always posed a considerable challenge, as this area serves crucial functional and esthetic roles. Being diagnosed and subsequently treated for facial tumors can have an immense psychosocial impact on a patient, as the resulting defects are often disfiguring, and lead to an inability to masticate, swallow, and speak clearly. Provision of an immediate facial and dental prosthesis at the time of surgery can limit these side effects and help reduce mental duress on these patients and their families, as well as aid in the process of rehabilitation.

The Effects of the Refugee Crisis on Age Estimation Analysis over the Past 10 Years: A 16-Country Survey.

Dental age estimation (AE) tests are routinely done on living and deceased persons. There is anecdotal evidence suggesting an increase in age estimations due to the refugee crisis. Our aim is to determine the reasons and methods for performing dental AE tests in both living and deceased individuals.

Nasal reconstruction of a patient with complete congenital arhinia: A clinical report.

Complete congenital arhinia is a rare embryonic disorder of unknown etiology. This is a clinical report of the prosthetic nasal rehabilitations done in the early childhood and adolescent stages of a patient with complete congenital arhinia. Additive manufacturing techniques for creating presurgical planning models to assist in the creation of new nasal passages are also described.

Applications of rapid prototyping technology in maxillofacial prosthetics.

Purpose: The purpose of this study was to compare the accuracy, required time, and potential advantages of rapid prototyping technology with traditional methods in the manufacture of wax patterns for two facial prostheses.

Materials And Methods: Two clinical situations were investigated: the production of an auricular prosthesis and the duplication of an existing maxillary prosthesis, using a conventional and a rapid prototyping method for each. Conventional wax patterns were created from impressions taken of a patient's remaining ear and an oral prosthesis.

Prosthodontic treatment of the edentulous adult cleft palate patient.

Clefts of the upper lip and plate are relatively common, yet dental treatment of these patients is still very poor and many grow up suffering dental neglect. Dental practitioners should become involved in the treatment team as dental needs are present from birth to death. Adult cleft patients often need tooth replacement with obturation of any residual clefts.

A mechanically retained, four part oral and facial prosthesis: a clinical report.

The design of a prosthesis depends not only on anatomical and physiological factors, but also needs to encompass patient's socio-economic limitations and psychological needs. A four-part prosthesis for a patient with a maxillary and orbital defect was designed to be easy for the patient to insert, remove and clean, retentive without requiring sophisticated attachments or the use of adhesives, and made from economically viable materials. The denture was attached to an acrylic resin core which in turn clipped into a silicone glove obturator.

Prosthodontic rehabilitation of a patient with total avulsion of the maxilla: a clinical report.

Patients with complete avulsion of the palate may require extensive surgical and prosthodontic rehabilitation. The prosthesis should replace not only missing teeth but also lost soft tissues and bone, including the hard palate, residual alveolar ridges, and in some situations, the soft palate. This clinical report describes the prosthetic rehabilitation, after appropriate surgical options had been exhausted, of a patient with bilateral traumatic avulsion of the maxilla.
