Lecture 1: Archwise Distraction Osteogenesis

Distraction osteogenesis is a magic tool in medicine. It is used in different areas of dentistry and medicine.For the treatment of some clinical problems,it is the only clinical method which is indicated.General knowledge about distraction osteogenesis is that;It is a linear procedure.Here the question comes;Is it possible to achieve archwise distraction?
We had begun to study on this topic almost about 20 years ago and at the end we were able to develop a successful method to achieve curvilinear distraction.
AWDA – Archwise Distraction Appliance – is a rigid, tooth-borne, custom-made appliance that is developed to control the distraction vector with double archwire system.
In this presentation this method will be introduced and discussed on some different clinical cases.

Lecture 2: Zygomatıc Implant Supported Openbıte Treatment

Skeletal openbite is known as the most challenging mallocclusion to treat.General principle in treatment is to correct the affected morphegenic pattern. True treatment requires the impaction of the overerupted maxillary posterior segment, achieve anterior rotation of the mandible and correct the affected skeletal pattern. Orthognahtic surgery is the only proven method which is used to impact the maxilla succesfully and achieve the anterior rotation of mandible and correct the malocclusion.
Zygomatic implant supported openbite treatment is a method which was developed as an alternative to orthognahtic surgery. In this procedure, two orthodontic miniplates are fixed in the zygomatic buttress area bilaterally and the extentions are bent in the form of a hook. Openbite appliance with acrylic caps covering the posterior teeth bilaterally, including the canines are connected by two palatal bars. Coil springs are extended between the appliance and the hooks of the zygomatic implants. In this force system three independent forces are created to be used for the impaction of maxillary posterior segment;
• Force coming from coil springs
• Functional force transmitted through the body of the tongue to the palatal bars
• Force created by muscle tonus.
In this presentation, zygomatic implant supported openbite treatment method will be described in detail and some treated cases will be presented along with long term follow up results.
