High Palatoglossal Arch: A New Indication for Pre-prosthetic Surgery

Area of Science:

• Dentistry
• Prosthodontics
• Oral Surgery

Background:

• Maxillary denture fabrication requires careful assessment of the soft palate and palatoglossal arch anatomy.
• Achieving optimal masticatory function and esthetics is crucial for successful prosthetic rehabilitation.
• Retention of maxillary dentures can be compromised by specific anatomical variations.

Observation:

• A high palatoglossal arch was identified as a rare anatomical cause for the loss of posterior palatal seal.
• This anatomical anomaly directly impacted the retention of the maxillary denture prosthesis.
• The patient experienced challenges with masticatory function and denture stability.

Findings:

• The study highlights a high palatoglossal arch as a previously unreported cause of maxillary denture instability.
• Pre-prosthetic surgery was employed to address the anatomical obstruction.
• Successful surgical intervention restored the posterior palatal seal and improved denture retention.

Implications:

• Pre-prosthetic surgery offers a viable solution for complex denture retention issues caused by anatomical factors.
• This case expands the understanding of factors affecting posterior palatal seal and denture stability.
• Further research into surgical management of anatomical challenges in prosthodontics is warranted.
