Definitive Palatal Obturator Applications: A Systematic Literature Review
Abstract
1. Introduction
- Surgical resections performed to treat benign or malignant neoplasms, such as epithelial or salivary gland tumors involving the maxilla;
- Infectious diseases such as osteomyelitis or bone osteonecrosis caused by factors like radiation;
- Chronic inflammatory conditions, such as cocaine-induced midline destructive lesions (CIMDL) or granulomatosis with polyangiitis, leading to structural and functional alterations of the maxilla;
- Easy visualization of the defect site, allowing for early detection of recurrences;
- Reduced hospitalization time and costs;
- The possibility of avoiding a second surgical procedure;
- Immediate morphological and functional restoration of the oral cavity [19].

3.6. Evaluation of Bias
- (1)
- Selection Bias: Most of the analyzed studies consist of case reports or case series (91.5%), with a near-total absence of controlled or randomized studies. This constitutes a significant selection bias, as the reported cases do not represent a random or representative sample but rather clinical scenarios selected for their rarity, success, or academic interest. Consequently, the generalizability of the findings is markedly limited, reducing their applicability to routine clinical practice;
- (2)
- Publication Bias: Many studies report highly favorable outcomes, such as complete functional rehabilitation, absence of recurrence even in the long term (e.g., 10-year follow-up), or excellent aesthetic results. This trend suggests a significant publication bias, reflecting the higher likelihood of publishing cases with positive outcomes compared to those involving complications, therapeutic failures, or functional limitations. Such bias may lead to an overestimation of the clinical efficacy of the prosthetic approaches described;
- (3)
- Reporting Bias: A critical limitation is the lack of uniformity and completeness in clinical reporting. A substantial proportion of the articles lack essential information, including the classification of the maxillary defect (e.g., Aramany), the type of material used in the prosthesis, the impression technique (analog or digital), and the duration of follow-up. This reporting bias hampers comparative analysis across studies and compromises reproducibility, thereby limiting the ability to draw reliable conclusions regarding the relative effectiveness of the techniques described;
- (4)
- Language and Geographic Bias: Several articles originate from local, non-English-language journals or journals with limited indexing (e.g., Brazilian, Turkish, or Egyptian journals). This introduces both language and geographic bias, as the study selection may not accurately reflect the global literature but rather be influenced by language and database availability. This may result in underrepresentation of clinical experiences from regions with high scientific output (e.g., the United States, Western Europe, etc.) and conversely overrepresentation of less standardized reports;
- (5)
- Technological Bias: Lastly, a notable technological bias was observed due to the limited presence of studies utilizing digital workflows (CAD/CAM, 3D printing, and intraoral scanners). Only a minority of the articles mention the use of such technologies, and even fewer provide comprehensive digital protocols. This limitation reflects both a slow rate of technological adoption in certain clinical settings and a potential disparity in access to digital resources factors that should be considered when evaluating prosthetic solutions.
4. Discussion
4.1. Cause of Maxillectomy
4.2. Ideal Indications and Requirements
- Assisting the patient in performing natural functions such as speech, swallowing, and chewing by restoring oral functionality compromised due to the anatomical defect. The prosthesis should closely resemble natural tissues, enhancing not only function but also the patient’s aesthetics. Maintaining periodontal health is not only essential for oral rehabilitation but may also play a role in reducing the risk of neurodegenerative diseases such as Alzheimer’s [84];
- The prosthetic design should allow for easy and quick application, ensuring that the device remains securely and comfortably in place without causing discomfort or instability;
- The prosthesis should be made of durable materials capable of maintaining their physical, aesthetic, and functional properties over time, preserving their original polish and finish for a reasonable period. Chitosan has been shown to promote tissue regeneration and reduce microbial colonization in oral surgery applications [85];
- The prosthesis should be easy to clean, allowing for proper maintenance and oral hygiene, preventing plaque and bacterial buildup, and reducing the risk of infections or other complications.
4.3. Palatal Obturator
4.3.1. Characteristics of Palatal Obturator
4.3.2. Impression Taking Technique
4.3.3. Enhancement of the Palatal Obturator
- Attachment Systems: In this type of prosthesis, the maxillary prosthesis and the obturator are connected by an attachment system, allowing the patient to separate them for insertion, removal, and cleaning and then reconnect them in the mouth. This system is particularly beneficial for patients with limited mouth opening [93].
