Impaired healing following implant placement surgery: A case report of a modern‐day manifestation of scurvy

Clinical Advances in Periodontics, EarlyView.
Abstract Background Delayed wound healing following implant placement surgery is an uncommon complication, usually attributed to systemic (smoking and alcohol), local (severely inflamed tissues), or technical (poor suturing) factors. However, delayed wound healing after implant placement caused by severe hypovitaminosis C has not been previously ...
