📝 “What is ‘Combination Syndrome’ of the Maxilla & Mandible?”

8.9.24Quick Review #200 - #surgery #surgeon #doctorgallagher #oralsurgery #oralsurgeon #omfs #dentist #dentistry #dental #combinationsyndrome #maxilla #mandibleCombination Syndrome, also known as the Kelly’s Syndrome, is a complex of changes that occur in the oral cavity, particularly affecting the maxilla and mandible, as a result of wearing a complete maxillary denture opposing a mandibular distal extension removable partial denture. This condition was first described by Dr. George Kelly in 1972.Key Features:1. Resorption of the Premaxilla:• The anterior part of the maxillary alveolar ridge undergoes significant resorption. This is due to the excessive pressure from the complete denture against the premaxilla during mastication, leading to bone loss.2. Hypertrophy of the Maxillary Tuberosities:• The maxillary tuberosities often become enlarged. This is due to the excessive occlusal forces concentrated in the posterior maxilla, leading to compensatory tissue growth.3. Papillary Hyperplasia in the Hard Palate:• Papillary hyperplasia may develop on the palatal mucosa, typically due to ill-fitting dentures and the constant irritation of the mucosal tissues.4. Extrusion of Mandibular Anterior Teeth:• The natural mandibular anterior teeth may extrude or supra-erupt due to the lack of proper occlusal support and the altered occlusal plane, as the anterior maxilla resorbs and loses height.5. Loss of Alveolar Bone in the Mandibular Posterior Region:• The mandibular distal extension partial denture lacks proper support, leading to accelerated resorption of the posterior mandibular alveolar ridge.Consequences:A. Occlusal Plane Discrepancies:• As the changes progress, there is an alteration in the occlusal plane, which can lead to difficulties in achieving stable occlusion and proper masticatory function.B. Compromised Denture Retention and Stability:• The resorption of the premaxilla and enlargement of the maxillary tuberosities can lead to poor retention and stability of the maxillary denture.C. Increased Risk of Traumatic Ulcerations:• The altered ridge morphology and occlusal discrepancies can increase the risk of traumatic ulcerations and discomfort for the patient.References:1.
