Clinical Application Of Crown Lengthening Surgery And The Change Of Gingiva Margin Position Initial Study In A Short Time

Objective:to investigate crown lengthening for the treatment of a variety ofreasons leding to subgingival root, or the clinical crown is too short to affect the toothpreparation and restorers, as well as uncoordinated affect the appearance of individualanterior teeth, the gingival margin and adjacent teeth, the gingival margincrownlengthening surgery to better meet the repair needs as well as periodontal health andstability.To observe the crown lengthening in the treatment and aesthetics in clinicaleffects and postoperative short-term changes in the gingival margin position.Methods:we collected17patients with22teeth crown lengthenin surgery case.Preoperative knowledge of general condition of patients, preoperative radiographs taken,check the tooth root and alveolar bone, determine the operation scheme. Preoperativepreparation of diagnosis model, when necessary the use of hard plastic film productionstents as measurement points. Preoperative dental, periodontal examination. For patientswith a detailed explanation of operation to eliminate patients’ fear, periodontal treatmentof plaque control, to prevent postoperative infection. Line of crown lengthening surgery,with the biologic width as the benchmark, determines the operation method, operationin strict accordance with the aseptic operation, intraoperative recording of various indexchanges. Postoperative oral health education to patients, a week after follow-up release.And in1weeks after operation,4weeks,6weeks,1months after the repair, the conduct ofclinical periodontal examination. In6weeks after operation8weeks of permanentrepair.Results: the clinical assessment standard: general from the patient’s subjectivefeeling and postoperative restoration effect to reflect the operation success. Aestheticcrown lengthening surgery, in addition to the above criteria, we need to consider theaesthetic effect. In the collection of the17cases, patients of the repaired effect are givendefinitely. There were14cases of think very satisfied, no loosening of teeth, no obvious periodontitis, no fistula, masticatory function good, solid edge restoration, close. Therewere1cases of gingival emergence mild inflammation, patients with poor oral hygiene,after supragingival scaling and performed on patients with oral hygiene instruction afterthe gingiva, good recovery. There were1cases of teeth on the1postoperative years,because the teeth bite tight, cause root fracture, while patients with long-term use ofcalcium antagonists in lowering blood pressure,3months after operation and obviousgingival hyperplasia. There are1cases of patients with food impaction.Conclusion: to observe17patients with22teeth of crown lengthening surgerytreatment, the results showed that, due to fracture of crown, caries etiological causes oftooth defect broken end in subgingival situation, adopts the biological width principle[3]of crown lengthening can meet the requirements of repair and gingival health andstability of the.At the same time to improve short clinical crowns, to facilitate retentionof restoration and periodontal health effect.
