Abstract: BACKGROUND: All-ceramic cantilever bonded bridge has become a hot topic in the clinical aesthetic restoration of anterior teeth due to its advantages in treatment time, invasiveness, aesthetics and price.
OBJECTIVE: To summarize the solutions to the clinical technical difficulties of all-porcelain cantilever bonded bridge and its advantages in the application of anterior teeth, and to introduce the clinical follow-up methods of the existing all-porcelain cantilever bonded bridge, in order to provide clinical and scientific guidance in the field of aesthetic repair of partial dentition defects of anterior teeth.
METHODS: The articles published from 1955 to 2021 were retrieved by the first author on Web of Science, PubMed, CNKI, and Wanfang databases. The English search terms were “denture, partial, fixed, resin-bonded, resin bonded bridge, Maryland bridge, adhesive bridge, single-retainer, all-ceramic”. The Chinese search terms were “bonded bridge, Maryland bridge, adhesive bridge, all-ceramic, cantilever, single-retainer”. Totally 60 articles were summarized for review after screening.
RESULTS AND CONCLUSION: (1) Effective surface pretreatment with zirconia ceramic material could prevent the occurrence of fracture. Designing the retention form of the box-shaped hole near the gap side and the nail hole at the bulge of the tongue is one of the current consensus of experts, which can effectively reduce the occurrence of bonded bridge shedding and improve the long-term retention effect. Under the condition of meeting the indications, the all-ceramic cantilever adhesive bridge has the advantages of low incidence of complications such as caries and periodontal disease, good aesthetic effect, and long retention time, and can be used as a permanent restoration. (2) For clinical studies, in addition to counting the basic success rate of retention rate, it is recommended to simultaneously use the oral health-related quality of life questionnaire, satisfaction questionnaire, and the American Public Health Association prosthesis evaluation criteria to comprehensively evaluate the repair effect. (3) It should be noted that different studies have defined the retention rate and success rate differently, which makes certain deviation for data statistics. Therefore, the actual clinical effect of all-ceramic cantilever bonded bridge is worthy of further investigation.
