Correct answer: B — To eliminate premature contacts and interferences that contribute to TMD symptoms

Occlusal adjustment (selective grinding/equilibration) involves the selective reshaping of occlusal surfaces to eliminate premature contacts in centric relation and excursive interferences (working and non-working side). It is an IRREVERSIBLE procedure that should only be performed after reversible therapies (splint, physiotherapy, medication) have stabilised the condition and occlusal discrepancies are confirmed as contributing factors. It is NOT a first-line treatment for TMD.
