“…dISCuSSIoN RME promotes an increase in transverse dimensions and in the perimeter of the upper dental arch with a real gain of bone at the level of midpalatal suture. 10,11 In the present case, intercanine expansion of 11 mm with intermolar expansion Complications that are related to the expansion appliance include its impingement on palatal soft tissue, loosening (more common with bone-borne distractors 12 ), and breakage and stripping or locking of the appliance screw.

Transverse maxilla-mandibular discrepancies are a major component of several malocclusions. Surgically assisted rapid palatal expansion (SARPE) is a common treatment modality for older patients in the correction of a maxillary transverse deficiency. In such cases, retention of the appliance plays an important role and this becomes a problem in patients having enamel hypoplasia. Therefore, the design was modified of a tooth-borne rapid maxillary expansion appliance with provision for miniscrew skeletal anchorage in a Class II malocclusion case having anterior open bite with bilateral posterior crossbite and enamel hypoplasia.

“…In the case of overloading or premature loading, the metal-bone interface fails and the screws become loose. Loose or dislodged devices have been mentioned in clinical studies (Neyt et al, 2002) and in experimental studies (Gefen, 2002;Schulten et al, 2002).…”

This report describes osteoclastic bone resorption around intraosseous fixation screws in rat and pig mandibles. These screws supported distraction devices and provided for neutral fixation following the distraction period. Progressive clinical instability of bicortical screws and radiographic and histologic evidence of osseous resorption were frequent findings. In rats, clinical evaluation revealed screw loss and/or loosening in 50% of the rats between 11 and 30 days of neutral fixation. Radiographic signs of resorption were apparent around 60% of the screws that were in place at the end of the observation period. The total rate of resorption or loss was 64 of 80 screws (80%). Histologic examination showed partial or extensive osteolysis around the screw holes in 87% of screws that were clinically fixed in the bone at sacrifice. In histologic sections of porcine specimens, osseous resorption around identifiable screw holes was present in 75% of the cases, and showed progressive increase in resorption with time. Osteoclastic resorption was common around bicortical screws that were evaluated after they had served for osseous stability.
