Full-Mouth Rehabilitation of Generalized Enamel Hypoplasia Using Hobo’s Twin-Stage Technique: A Case Report

Full-mouth rehabilitation in patients with generalized enamel hypoplasia is clinically challenging because of compromised enamel quality, esthetic impairment, dentinal sensitivity, caries susceptibility, and disturbed occlusal function. This case report describes the comprehensive rehabilitation of a 25-year-old male patient who presented with generalized yellow-brown discoloration, rough and pitted enamel surfaces, posterior caries, loss of canine guidance, unilateral crossbite, and poor smile esthetics. Following diagnostic evaluation and pre-prosthetic management, treatment was planned using Hobo’s Twin-Stage procedure to establish a stable group-function occlusal scheme. Diagnostic wax-up was completed using Conditions 1 and 2 on a semi-adjustable articulator, followed by provisionalization to verify vertical dimension, esthetics, phonetics, occlusal comfort, and functional adaptation. Final restorations were fabricated using monolithic zirconia in the posterior region and multilayered zirconia in the anterior region. The restorations were cemented after bisque trial, marginal verification, and occlusal adjustment. At follow-up, the patient demonstrated satisfactory esthetic improvement, stable occlusion, healthy periodontal response, maintenance of vertical dimension, and absence of temporomandibular discomfort. Clinical Relevance to Interdisciplinary Dentistry: This case highlights the importance of coordinated prosthodontic, restorative, periodontal, and occlusal management in treating generalized enamel defects. The approach demonstrates how interdisciplinary treatment planning can restore esthetics, function, occlusal harmony, and long-term clinical stability in complex full-mouth rehabilitation cases.
