Drug-induced gingival hyperplasia is defined as non-inflammatory enlargement of the gingival produced by drug therapy other than local irritation such as dental plaque related inflammation. According to their therapeutic actions, medications causing gingival hyperplasia are as follows; Anticonvulsants, Immunosuppressant, calcium channel blockers. Mechanism for gingival hyperplasia is not well understood. Treatment choices for gingival hyperplasia can be 1) careful oral hygiene care by patients and dental professionals, 2) reduction the dose or change to another drug may bring about partial or complete regression and 3) surgical excision. This case report describes prosthetic restorations in a drug-induced gingival hyperplasia patient after surgical excision and tissue conditioner relining. The patient had been taking Nifedipine (Calcium channel blocker) for 10 years for hypertension and stroke and presented moderate developed gingival hyperplasia due to poorly retained partial dentures and poor oral hygiene. Multiple residual roots were serially extracted and the hypertrophic gingiva was surgically removed by means of gingivectomy. And then, complete denture on the maxilla were delivered and 6-unit implant supported fixed prosthesis on the mandible were installed. In the drug-induced gingival hyperplasia cases, implant supported fixed restoration can be successfully used for gingival stability.
