[Deep bite correction in adult patients].

Excessive occlusal force caused by deep bite is an etiology of alveolar bone resorption as well as premature loss of permanent teeth. Deep bite correction in adult patients should comprise of intrusion and/or proclination of anterior teeth in order to prevent skeletal alteration and relapse. The objective of the article was to present indication and mechanics of intrusion and proclination of anterior teeth with a case report of the patient who had a problem of masticatory system especially temporomandibular joint, cuspid protection system and deep bite.

[Case report: skeletal Class III correction by orthodontic means].

Skeletal Class III therapy of the two siblings with a protraction headgear was reported. The treatment result indicated that skeletal and dental malocclusion could be achieved by redirection of maxillary and mandibular growth with force system comprising 400 grams maxillary protraction and 1000 grams mandibular retraction when the treatment was performed at the appropriate time.

[Maxillary features following protraction headgear therapy in skeletal Class III patients].

The objective of the research was to scrutinize maxillary alteration of skeletal Class III patients following protraction headgear therapy. The sample comprised of 15 patients (6 males, 9 females) aged 8-13 years. According to Sassouni Analysis, the maxilla was retrognathism whereas the mandible was prognathism. All of them were treated with fixed appliance and protraction headgear. Orthopedic force system included maxillary protraction with 400 gram force, mandibular retraction with 1000 gram for 12-14 hours per day. Alteration of the maxilla was scrutinized from consecutive lateral cephalograms prior to orthodontic treatment, immediate posttreatment and 2 years of follow up. The result indicated that orthopedic force enhanced the anterior portion of the maxilla to move downward and forward significantly, without rotation and relapse.
