Abstract

Torus palatinus (TP) is a benign, slow-growing bony protrusion of varying shape and size, most commonly situated along the sutura mediana in the frontal or back third of the hard palate. A large discrepancy in the resilience of its musocal envelope and adjacent mucosa (resilient zones by Shroeder), especially in cases with large protrusions, can bring about the problems in the manufacture of total prostheses and especially in wearing them („rocking“, fracture of the prosthesis along the palatal midline, injury to the mucosa in the region of TP, etc.). This paper presents in extenso the plan of the administered prosthetic treatment of a female patient aged 62 years, admitted to the clinic because of total edentulousness of the upper jaw and a very distinct TP. After clinical examination and necessary consultations with an oral surgeon, using the method of selective decompression of TP during the functional imprint acquisition, an upper total prosthesis was manufactured with a small chamber in the region. Possible complications mentioned above were thus avoided, and the patient adapted to the prosthesis completely after one common reocclusion and two control visits.

Highlights

This paper presents in extenso the plan of the administered prosthetic treatment of a female patient aged 62 years, admitted to the clinic because of total edentulousness of the upper jaw and a very distinct Torus palatinus (TP)
Since the vault of the bony palate constitutes a great deal of support to the upper total prosthesis, it should be given particular attention regarding the prognosis of prosthesis success
Numerous different shapes of the vault have been categorized into four basic clinical forms [2]: tetragonal form, with moderately prominent concavity, is the most common form, prognostically the most favorable regarding retention and stabilization of total prosthesis, since the mucosa too is optimally resilient; triangular form, with very prominent alveolar ridges, is an unfavorable form with poor wearing prognosis for upper total prosthesis; and flat palate, with marked resorption of alveolar ridges and minimal resilience of the mucosa, is the least favorable form associated with very poor prognosis regarding satisfactory retention of total prosthesis
