ABSTRACT
Objective@#To study the clinical effect of a polyetheretherketone (PEEK) bonding bridge on the loss of 3 internal incisors in patients with periodontitis.@*Methods@#This study was reviewed and approved by the ethics committee, and informed consent was obtained from the patients. Thirty-eight patients with periodontitis and 3 missing central or lateral teeth were selected to undergo restoration with a PEEK bonding bridge and then returned to the hospital 3, 6, 12, and 24 months after the restoration was completed. The survival rate of the restorations was assessed by the modified USPHS/Ryge criteria. The plaque index, gingival index, periodontal probing depth and attachment loss of the abutments were recorded, and the changes in periodontal tissues after restoration were observed and compared.@*Results@#Over 24 months of clinical follow-up observation of 38 patients, only 1 patient underwent secondary bonding after partial debonding (evaluated as grade B), while bonding was successful in the other 37 cases (evaluated as grade A). The plaque index, gingival index and periodontal probing depth were significantly lower after restoration than before (P<0.05). There was no significant change in attachment loss between before and after restoration (P>0.05).@*Conclusion@#For periodontitis patients missing 3 internal incisors, short-term PEEK bonding bridge repair has good clinical efficacy.
ABSTRACT
Objective To study the effect of unmovable splint therapy in patients with moderate and severe periodontitis. Methods Twenty periodontitis cases with loosened anterior teeth were treated with unmovable splints after the basic periodontal therapy. The clinical effect and periodontal index were evaluated in the sixth month, the first year, the second year and the third year. Result The success rate was 90 percent three years after the restoration.Conclusion Unmovable splint therapy is one of the effective therapies in the treatment of periodontitis.
ABSTRACT
Objective To investigate the clinical effect of high strength periodontal splint combined with tooth powder in the treatment of moderate and severe periodontal disease in the elderly. Methods The control group was treated with Iodine Glycerol on the basis of the high strength periodontal splint. The study group was treated with the dental splint on the basis of the high-strength fiber periodontal splint. The clinical efficacy of two groups of elderly patients with moderate or severe periodontal disease was recorded. The data were input into SPSS software and analyzed and concluded. Results The analysis shows that the treatment group elderly patients with moderate and severe periodontal dise Zase treatment effect is better than the control group, the total effective rate of the study group is 89.80%, compared with 75.51% in the control group, the difference between the two groups was statistically significant (P<0.05). Conclusion The use of high strength fiber periodontal splint and tooth powder for the treatment of senile moderate and severe periodontal disease can significantly improve the efficacy of patients, and is conducive to the protection of their quality of life, physical and mental health.

ABSTRACT
Objective To investigate the clinical effect of periodontal fiber retention periodontal splint and Periocline combined treatment for severe tooth. Methods the control group was given routine retention of fiber periodontal splint treatment, study group in retention of fiber periodontal splint treatment combined with periocline. The changes of PLI, BI, PD and AL before and after treatment in two groups of patients with severe periodontal disease were recorded. The data were input into SPSS software and given statistical analysis. Results The detection of two groups of PLI, BI, PD, AL and other indicators of no significant difference between before treatment; after treatment of different options of group AL, PD decreased than the control group (P<0.05); PLI of the study group after treatment, BI decreased significantly than before (P<0.05), the control group on the index no obvious change than before. Conclusion The application of retention of fiber periodontal splint combined with Periocline treatment of severe periodontal disease can significantly improve the curative effect, is conducive to the protection of the quality of life.
ABSTRACT
Objective: This clinical study evaluated the success of two different splint materials bonded on periodontally treated mobile teeth. Material and Methods: A total of 14 patients were included in the study. Patients were randomly assigned to the groups to receive either with wire composite splint (WCS) or fiber-reinforced composite splint (FCS). Clinical periodontal parameters were performed and periotest values were recorded at baseline, and after 6 and 12 months. Patients were asked to complete a self-administered questionnaire after the splinting procedures. Failure types for the splints were categorized. Results: Baseline Plaque index (PI) values showed significant decrease at 6 month follow up in the WCS (p = 0.0019) and FCS (p < 0.0001) groups and remained stable after 12 months (WCS; p = 0.36, FCS; p = 0.63). During the course of the study, PD and RD values exhibited no change between and within groups. Clinical parameters including Pocket depth (PD), Gingival recession (GR), PI and Bleeding on probing (BOP) were stable at 6 and 12 months follow-up period. In 6 patients (4 FCS, 2 WCS), reparable failures occurred during the observation period. In four patients (3 FCS, 1 WCS) splints failed completely and were removed. The periotest values of the failing teeth ranged between 47.3 and 50. In 3 patients in the WCS and 1 patientin the FCS group, periotest values were ≥ 40 but no splint failures were observed. Conclusion: FCS tends to show increased mechanical limitations compared to WCS. Teeth with periotest values above 40 may be more prone to splint failures independent of the splint material.
Objetivo: Este estudo clínico avaliou a permanênciade dois materiais diferentes utilizados para contenção de dentes com mobilidade tratados periodontalmente. Material e Métodos: Um total de 14 pacientes foram incluídos no estudo. Os pacientes foram distribuídos aleatoriamente em grupos para receber contenção com fio de aço inoxidável (FA)e resina ou resina reforçada por fibra de vidro (FV). Os parâmetros clínicos periodontais foram realizados e os valores do Periotest foram registrados no início do estudo e após 6 e 12 meses. Os pacientes foram convidados a preencher um questionário após os procedimentos de contenção. Foram classificados os tipos de falhas para as contenções. Resultados: Os valores de índice de placa de base (IP) apresentaram diminuição significativa aos 6 meses de acompanhamento nos grupos FA (p = 0,0019) e FV (p < 0,0001) e manteve-se estável após 12 meses (FA, p = 0,36, FV, p = 0,63). Durante o período do estudo, a profundidade de sondagem (PS), recessão gengival (RG) e nível clínico de inserção (NCI) não apresentaram mudança entre e dentro dos grupos. Os parâmetros clínicos incluindo PS, RG, NCI, IP e sangramento a sondagem ficaram estáveis em 6 e 12 meses de período de acompanhamento. Em 6 pacientes (4 FA, 2 FV), ocorreram falhas reparáveis. Em quatro pacientes (3 FV, 1 FA) a contenção falhou completamente e foram removidos. Os valores Periotest dos dentes que as contenções falharam variaram entre 47,3 e 50. Em 3 pacientes no grupo FA e 1 paciente no grupo FV, os valores Periotest foram ≥ 40, mas não foram observadas falhas na contenção. Conclusão: O grupo FV tendeu a mostrar aumento das limitações mecânicas em relação ao FV. Dentes com Periotest valores acima de 40 podem ser mais propensos a falhas de contenção independentes do material utilizado.
