Objective: This course will guide surgeons and prosthodontists through the steps to transform a skeletal deformity into a Class I prosthetic rehabilitation for a single or double All-on-X based on the most reduced bucco-lingual prosthetic platform to obtain good speech, hygiene and ideal mastication. Presenters will discuss the 1,000 patients who were treated for a single or double arch under IV Sedation to restore a failing dentition or edentulous jaw. All patients had facial photographs, CT Cone-Beam images and dental models mounted on Sam’s Articulator. Clinical evaluation, cephalometrics and model surgery were used to plan and obtain the diagnosis and treatment plan. The results included 122 patients showed a skeletal deformity, 104 were treated to compensate the malocclusion into a Class I, 12 patients presented a Class II division 1 with anterior mandibular postural position into a Class I requiring minimal compensation, and six patients were rehabilitated into a mild compensated Class III because of the deformity magnitude. The implants were inserted either buccally or lingually and prosthetic abutments with different inclinations were utilized to aim toward the compensation required. Narrow arches were compensated by inserting the fixtures as buccally as possible or lateral to the alveolar ridge. The conclusions: compensating surgical-prosthodontics improve function and esthetics.
Learning Objectives:
At the conclusion of this presentation, participants should be able to:
Identify and treat a skeletal deformity compensating the malocclusion. Avoid All-on-X complications. Improve the biomechanics model by implant positioning and possibly increase the number of fixtures.
Demonstrate compensating surgical-prosthodontics improves facial esthetics. Obtaining a Class I canine and molar in a patient with a skeletal deformity permits a wide, attractive and functional smile.
Determine how to avoid orthognathic surgery in most instances. Proper implant positioning and inclined prosthetic abutments allows the transformation of most skeletal discrepancies or improve facial esthetics importantly.
