Chapter 16. Surgical Preparation of the Oral Cavity for Prosthetic Treatment (A.V. Shchtsipsky)
6 topics with concise breakdowns: definitions, key facts, and class questions.
Successful prosthetic treatment is often impossible without proper preparation of the prosthetic bed. Chapter 16 is dedicated to surgical interventions that create optimal anatomical conditions for reliable fixation and stabilization of dental prostheses.
This section provides a detailed analysis of both hard and soft tissue preparation. You will study techniques for alveoloplasty and the removal of exostoses (including the palatal torus), as well as procedures on the oral mucosa: vestibuloplasty, frenuloplasty of the lips and tongue, and excision of excess soft tissue (for example, in cases of hyperplasia or a "flabby" ridge.
During practical classes and exams, instructors most frequently ask about the indications and contraindications for specific techniques. Be prepared to justify your choice of vestibuloplasty method (according to Clark, Edlan-Mejcher, etc.) and clearly explain how leaving exostoses or a short frenulum will lead to rocking, denture dislodgement, or chronic mucosal trauma.
Why is an effort made not to touch the palatal root during amputation in the maxilla?
The palatal root performs the main supporting function for the upper molars. If it is extracted, the tooth is highly likely to lose stability.
How to prevent resorption of the autograft?
This requires the most precise adaptation of the bone graft to the recipient bed and its rigid fixation with microscrews.
Why did modern surgery abandon open healing in vestibuloplasty?
Techniques with open wound management (including under iodoform gauze) provoke the formation of coarse scars. This scar tissue hinders quality prosthetics no less than the initially shallow vestibule.
Can the surgery be performed on both jaws simultaneously?
Yes, simultaneous intervention on the upper and lower jaws is permitted when using the silicone complex. The stents stent technique usually does not imply this.
Why does atrophy of the alveolar process occur in secondary edentulism?
The main cause of atrophy of the alveolar process of the maxilla and the alveolar part of the mandible is the lack of adequate masticatory load after tooth loss.
What is the essence of Limberg frenuloplasty?
This is a procedure to eliminate a short labial frenulum. The essence lies in incising opposing triangular flaps, transposing them to lengthen the frenulum, and closing the wound primarily.
