Treatment of trauma from occlusion and periodontal abscess caused by improper size of prosthetic crown: A case report

Research output: Chapter in Book/Report/Conference proceedingChapterpeer-review


Introduction: Application of fixed prosthetics can cause periodontal problems. Improper sizing and placement of fixed prosthetics can endanger the periodontal system in several ways, including causing gingival inflammation problems or trauma from occlusion that inhibits attachment and causes bony defects. We reported the treatment of occlusional trauma caused by improper prosthetic crown sizing. Case report: A 75-year-old man presented with complaints of pain when chewing and eating. He underwent anamnesis, dental, periodontal examinations and radiography. Treatment planning was made from initial therapy through the rehabilitation phase. After 3 months he was re-evaluated. The patient's main complaint of pain disappeared after coronoplasty, but this treatment did not reduce the pocket depth. A flap operation that used a combination of DFDBA and pericardium membrane successfully reduced pocket depth, loss of attachment and intrabony defects after 3 months of follow-up. Conclusion: Improper fixed prosthetic sizing can cause trauma from occlusion, pain, increased pocket depth and loss of attachment. In this case, coronoplasty successfully eliminated pain. Flap surgery is an effective means of reducing pocket depth and mitigating loss of attachment. Periodontal professionals should consider the prosthetic implant's size, placement and the occlusal loading of periodontal ligament as a result of prosthetic placement so as to prevent traumatic occlusion.
