This article reviews the literature published from 1971 to 2015 concerning preliminary impression techniques used in making impressions for patients with microstomia based on various tray designs. Among these are the flexible trays and the sectional trays used with different modes of reassembling the segments extra orally after the impression is made. Due to the restricted mouth opening, insertion and removal of the impression trays is extremely cumbersome and various modifications of the trays have been used in the past. A maximum oral opening which is smaller than the size of the tray can make prosthetic treatment challenging. This is due to the tongue rigidity and the decreased oral opening. The difficulty starts with the preliminary impression making. The Prosthetic rehabilitation of microstomia patients presents difficulties at all the stages. The success of the prosthetic technique primarily depended on the extent of the microstomia and the nature of the cause of the microstomia.Įven though the patient acceptance of the prosthetic techniques summarized in the systematic review were high, long-term success rates for each option could not be assessed because of the short follow-up time in most of the included case reports and series. Modified forms of oral prostheses ranging from sectional, flexible, collapsible and hinged dentures to implant-supported prosthesis were fabricated to overcome the limited mouth opening. The review revealed the use of a modified impression technique with flexible and sectional trays to record impressions in patients with microstomia. A total of 34 cases (including 32 case reports and 1 case series) were finally included in the qualitative analysis. The remaining 172 articles were assessed for eligibility, and 139 articles were removed because they did not satisfy the inclusion criteria.
INTAGLIO DENTAL SERIES
Only case reports and case series on prosthetic rehabilitation in microstomia patients published in the English language were considered eligible.Ī total of 212 records were identified from the database search. Three investigators reviewed and verified the extracted data. The purpose of this paper is to systematically review all the prosthetic techniques that have been used in the oral rehabilitation of patients with microstomia.ĭata sources, including PubMed, Google Scholar, SCOPUS and Web of Science, were searched for case reports and case series published through September 2017. Prosthetic techniques commonly employed for the rehabilitation of edentulous patients might not be adequate in the treatment of patients with microstomia. Evaluation of quality of life and denture retention of mandibular overdentures using short profile versus self-aligning attachments in completely edentulous patients with limited interarch space. TO CITE THIS ARTICLE Al-Adl AZ, Mostafa MH, Al-Sourori AA. Regarding overdenture retention, low profile attachments presented higher retention values than self-aligning attachments at the beginning of the study but faster retention loss than self-aligning attachment over time. Conclusion Both types of attachments offer good oral health-related quality of life for completely edentulous patients with limited inter-arch space. Regarding overdenture retention, the low profile attachment group showed statistically significant higher retention force compared to that of the self-aligning group at the time of insertion however, there was no statistically significant difference between two groups at the 6 months follow-up. Results Regarding oral health-related quality of life, there was a statistically significant improvement. Low profile attachments were used in group I and self-aligning attachments in group 2. Material and Methods Forty-two patients were carefully selected, complete dentures fabricated, then two implants were placed in the canine region for each patient.
Aim Clinical evaluation of the effect of using low profile versus self-aligning attachment mandibular over-denture on oral health related quality of life and denture retention.
