Methods: In order to improve the therapeutic effect of oral cavity repair, a total of 70 patients with "dentition defect" who were treated in our hospital from February 2018 to February 2020 were selected and divided into conventional group (conventional repair treatment) and implant group (dental implant restoration technology), 35 cases in each group. The satisfaction and total effective rate of chewing and pronunciation function, stability and aesthetic function of patients in two groups were analyzed. Results: the total effective rate of "Implant group" was obviously superior to that of the conventional group in pronunciation, chewing, aesthetic function, stability enhancement and satisfaction (P < 0.05). Conclusion: compared with the conventional treatment, the "oral implant" repair technique in our hospital has a significant effect on the dentition defect patients, with good stability and better recovery of chewing, pronunciation and other functions.展开更多

[1] In the traditional classroom teaching, the teachers mainly teach the teaching content through the language, which is more abstract and boring for the students who first contact. The content of dentition defect course is relatively fixed, which is suitable for case-based learning (CBL). CBL teaching curriculum design of dentition defect mainly includes three aspects: pre-class preparation, classroom guidance and demonstration, after-school teaching evaluation and feedback [2]. Before class preparation, teachers should carefully prepare typical cases, set questions and group students according to the syllabus;in classroom teaching, students carry out group discussion under the guidance of teachers and look for answers;after class teaching evaluation and feedback are conducive to teachers to summarize and improve the curriculum and promote the improvement of teaching quality.展开更多

This study aimed to evaluate the clinical performance of a ceramic bridge with auro-galvanoforming primary coping and Ni-Cr pontic for restoration of dentition defects. Methods In total, 114 ceramic bridges with auro-galvanoforming （primary coping and Ni-Cr pontic） were placed in 112 patients with dentition defects. Among them, 83 bridges in 82 patients were available for follow-up after 7 years. We evaluated marginal integrity, color match, gingival inflammation, fracture of ceramic bridges, and recurrent caries. Results Marginal integrity of the ceramic bridges was perfect in all patients. Most ceramic bridges maintained their original color. Fracture was found in three bridges; the rest were free of fracture, breakage, and loosening. Recurrent abutment caries were not found. Ceramic bridges with auro-galvanoforming （primary coping and Ni-Cr pontic） produced satisfactory clinical outcomes -- equivalent to the conventional porcelain-fused-to-metal restoration. This technique is especially useful for dentition defects of the molar area and is cheaper than restoration with noble metal bridges. Conclusions Ceramic bridges with auro-galvanoforming （primary coping and Ni-Cr pontic） performed well for the restoration of dentition defects during this follow-up period. More studies are warranted to further evaluate this technique as an alternative to the conventional porcelain-fused-to-metal restoration.展开更多
