Patient:
A patient presented with malocclusion caused by generalized periodontal disease, subgingival caries, and poorly designed restorations and prostheses. Occlusal reconstruction was carried out in this case according to occlusal guidance that was determined based on mandibular head movement, following periodontal surgery. The emergence profile of the prostheses was made to match the periodontium.
Discussion:
By achieving an occlusal form, where the maxillary and mandibular molar teeth could be instantly separated through proper anterior guidance corresponding to the internal structure of the mandibular joint, it was possible to attain long-term stability while maintaining harmony with the temporomandibular joint without damaging the periodontium.
Conclusion:
Occlusal guidance corresponding to the internal structure of the temporomandibular joint is important for maintaining the stability of the periodontium, teeth and temporomandibular joint.
