Summary

Maxillary anterior fixed prostheses esthetics and function are impacted by residual alveolar ridge contour. Class I deficient ridges showed higher patient satisfaction and better esthetic scores compared to Class II or III.

Area of Science:

  • Dental Prosthodontics
  • Oral and Maxillofacial Surgery
  • Esthetic Dentistry

Background:

  • Maxillary anterior fixed prostheses can be compromised by deficient residual alveolar ridges.
  • Pontic adaptation to compromised ridges affects both esthetics and function.

Purpose of the Study:

  • To determine the effect of residual alveolar ridge contour on the esthetics and function of maxillary anterior fixed prostheses.
  • To evaluate patient satisfaction and objective esthetic outcomes based on ridge morphology.

Main Methods:

  • A cohort of 30 patients (13 male, 17 female; age 23-75) with maxillary anterior fixed prostheses were interviewed.
  • A structured interview assessed patient satisfaction with esthetics and function.
  • Pontic esthetics were evaluated using a 12-point esthetic index.

  • Residual ridge contour was classified using Siebert's classification (Class I, II, III).

    • Main Results:

    • Patients with Class I (buccolingual deficiency) ridges reported higher subjective satisfaction.
    • Objective esthetic index scores were significantly higher for Class I ridges (10) compared to Class II (7.4) and Class III (7.3) ridges (p < 0.05).

    Conclusions:

    • Residual alveolar ridge contour significantly influences the esthetic and functional outcomes of maxillary anterior fixed prostheses.
    • Ridge augmentation should be considered before prosthesis fabrication, especially for Class II and III ridge defects, to improve patient outcomes.
