Abstract:
It is complicated to decide the treatment plan of hopeless anterior teeth in esthetic zone due to severe periodontitis, periodontal-endodontic combined lesion or teeth trauma.The optional treatment plan for this kind of teeth includes retention after periodontal treatment, extraction and implant treatment, extraction and prosthodontic treatment and so on.To make an appropriate treatment plan, patients'' periodontal conditions, periodontal biotype, local anatomy, esthetic demand, economic condition and social psychological status should be comprehensively considered.A combine of periodontal, endodontic and orthodontic therapy may achieve a good treatment effect in hopeless anterior teeth with severe periodontal destruction, tooth extrusion and occlusal trauma.In this case, a 20-year-old female who presented with symptoms of bleeding on brushing and upper incisors loosening for 1 month came to the Department of Periodontology, Peking University School and Hospital of Stomatology.The clinical examinations revealed that the patient''s right upper incisor had signs of mobility (Ⅲ°), intrusion of 1-2 mm, and probing depth (PD) of 9-10 mm.The periapical radiograph showed that the alveolar bone of right upper incisor absorbed horizontally to the apex.And the patients showed Angle Ⅱ° malocclusion with Ⅱ° overbite in anterior teeth and maxillary protrusion.A diagnosis of aggressive periodontitis and Angle Ⅱ° malocclusion was made.The treatment of this patient lasts for 5 years which include periodontal initial therapy, orthodontic therapy, guided tissue regeneration (GTR) of right upper incisor and supportive periodontal therapy and the clinical result is fine.A hopeless upper incisor was successfully retained and the longtime clinical condition was stable.The strategy of retention of hopeless upper anterior teeth, the relationship of periodontal treatment and orthodontic treatment, and the indications of periodontal and orthodontic combined therapy were also discussed on the basis of this case.Generally, the positive factors in retention of hopeless teeth includes young age, absence of systemic conditions, strong motivation for maintaining the tooth, single root anatomy, integrated dentition, good response to cause-related therapy, intrabony alveolar bone defect, thick periodontal biotype, and regular supportive periodontal therapy.And in the progress of orthodontic therapy, regular supportive periodontal therapy and good plaque control is extremely important.
