Transpalatal distraction as a method of maxillary expansion.
نویسنده
چکیده
Conventional devices used for surgically assisted rapid palatal expansion are tooth-borne. Dental fixation entails a number of possible drawbacks such as loss of anchorage, skeletal relapse during and after the expansion period, cortical fenestration and buccal root resorption. A bone-borne titanium device with interchangeable expansion modules, used with a callous distraction policy, is presented.

Transpalatal distraction--state of the art for the individual management of transverse maxillary deficiency--a review of 50 consecutive cases.
Transpalatal distraction has been established as a technique for surgical assisted rapid palatal/maxillary expansion (SARPE/SARME) in order to correct transverse maxillary deficiency. From 2007 until 2013 bone borne transpalatal distraction devices have been inserted in 50 patients affected by transverse maxillary deficiency and transpalatal distraction has been performed by the same surgical t...
متن کاملPosterior transpalatal distraction with pterygoid disjunction: a short-term model study.
The transpalatal distractor (TPD) allows for maxillary expansion according to the concepts of distraction osteogenesis. Unlike tooth-borne, surgically assisted rapid palatal expansion devices, the bone-borne TPD is designed to avoid periodontal ligament compression, buccal root resorption, fenestration, tooth tipping, and orthodontic relapse during and after the expansion. When the distractor i...
متن کاملTranspalatal distraction osteogenesis prior to alveolar bone grafting in cleft lip and palate patients.
Alveolar bone grafting is a standard method for treating alveolar cleft. To ensure the best outcome, improving the arch form as well as soft tissue quality in the area around the cleft is recommended. In this study, 11 patients who presented with alveolar cleft and collapsed maxillary arch were treated in the following sequence: transpalatal distraction osteogenesis followed by soft tissue surg...
متن کاملProblems, obstacles and complications with transpalatal distraction in non-congenital deformities.
INTRODUCTION The transpalatal distractor is a bone-borne device that eliminates negative orthodontic effects during and after maxillary expansion. It produces virtually parallel expansion in the coronal plane. Orthodontic appliances can be installed at an earlier date than when tooth-borne expanders are used. Our aim was to improve the technique by reviewing the difficulties encountered during ...

INTRODUCTION The aim of this prospective study was to analyze the postexpansion positional changes of the maxillary halves and their initial stability after transpalatal distraction with a bone-borne distractor and standard corticotomies of the anterior, lateral, and median bony supports of the maxilla without pterygomaxillary disjunction. METHODS The sample consisted of 21 patients (15 femal...
