Oxtex dental and oral

The potential use of soft tissue expanders for dental and oral surgery applications is large and the market is growing. 

Currently available soft tissue expanders have not been used in in these areas so far due to their unsuitable expansion properties. The Oxtex soft tissue expanders address these shortcomings in a variety of different areas.

Cross bite

Cross bite is a significant misalignment of the upper and lower jaws resulting in anterior crossnbite (where the upper front teeth are in front of the lower teeth) or posterior cross bite (the opposite). The condition is both uncomfortable and painful and makes simple tasks such as eating very difficult. There is a high prevalence of crossbite in the Far East with 7-10% of the Malaysian population being affected. Most cross bite cases are never corrected and there are multiple techniques available to improve teeth alignment. In some cases, however, it is necessary to create a crack in the hard palate and move the two halves apart mechanically. In these cases additional soft tissue is needed in order to cover the newly formed bone. In partnership with the University of Oxford, Oxtex has secured a research collaboration with the University of Malaya to develop devices for the treatment of cross bite in humans.

Cleft palate repair

Cleft palates fall in the category of deformities at birth (congenital deformities). In the developed world surgical correction of a cleft palate is normally done between 9-12 months after birth whereas in developing countries such interventions may be done much later in childhood, or even adulthood. The surgical procedure to repair a cleft palate often requires tissue to be taken from the roof of the mouth to help bridge the gap. Occasionally, such an intervention may require more than one operation. Oxtex devices may be used in such cases to expand the mucoperisteum of the hard palate in order to generate additional soft tissue.

Dental implants

The main need for the Oxtex technology would be in all applications that require an augmentation of the jaw bone. Such bone augmentation is needed in 15-20 per cent of all dental implant operations in order to stabilise implants or to replace bone mass following trauma or cancer operations. Both scenarios require additional soft tissue. The main need exists for expanders with a delayed onset of expansion. Once inserted into the mucoperisteum of the gum the expanders would only begin to expand after the gum has healed. Existing soft tissue expanders do not allow for a delayed start in expansion or for expansion in one direction only. Both of these requirements are addressed by the Oxtex technology.
