Rehabilitation of oncology patients with hard palate defects part 1: the surgical planning phase

Abstract

This article is the first in a series of three papers that will discuss the conventional non-implant retained prosthodontic rehabilitation of oncology patients with surgically acquired hard palate defects. In this first paper, the dental challenges posed by the oncology patients will briefly be discussed. The interface between the specialist restorative dentist and the maxillofacial surgeon when planning the conventional dental rehabilitation of an oncology patient with a hard palate defect will be discussed in detail. Clinical Relevance: To highlight the importance of the restorative dentistry/surgical interface when planning a treatment for a patient requiring a maxillectomy and conventional obturation.

Biomechanical Stress in Obturator Prostheses: A Systematic Review of Finite Element Studies

“…Essentially, this is mainly because of the simplicity of design and wide coverage of Aramany's classification which can be observed when applied to the other different classifications. Despite this, Aramany's classification overlooked the vertical extension of the maxillary defect, and thus, those authors who followed Aramany classification mistakenly assumed it does not exists [2].…”

“…(1) The stress and displacement of MFPs are highly influenced by the sizes and characters of maxillary defects, availability of adequate undercuts, and health and position of the remaining dentitions (2) The stress is mainly concentrated on the resection side and the apices of the teeth next to the defect (3) Using DI in the nondefective of maxillary defect reduces the stress on the supporting structure as the implant share the stress with the abutments (4) Adding ZI in the defective side of dentulous and in the defective and nondefective sides in edentulous maxillary defect is considered a key factor in reducing the displacement of maxillofacial prostheses. It may also decrease the need to DI, the need to use clasps on the teeth next to the resection, and -to massive surgical free flap reconstruction…”

“…The patient's quality of life often collapses following the surgical resection of the tumor mass because of the corruption of function, speech, and aesthetics [1]. To overcomes the functional and psychological impact of the surgery, a surgical microvascular and/or prosthetic reconstruction must be carried out to improve the patient quality of life [2,3]. Surgical rehabilitation of maxillary defects is not always possible due to the lack of donor sites, size of the defect, general health of the patient, and the risk of morbidity [4].…”
