Abstract

Aiming at the current situation that the pre-porcelain veneer tooth preparation operation is difficult, prone to excessive grinding of tooth tissue, and pulp sensitivity in clinical practice, a digitally designed and manufactured personalized tooth preparation step-by-step indicator guide plate is invented. The reason is that the guide plate is designed and produced by digital methods, and it is used for precise tooth preparation of anterior dental veneers, and can realize precise tooth hard tissue grinding step by step to achieve the purpose of minimally invasive. The step-by-step guide indicates tooth preparation in three steps: the first step, using the incisal guide, indicates the incisal and proximal preparation; the second step, uses the labial guide, indicates the labial preparation; the third step, uses the gingival margin guide , indicating gingival margin preparation. The guide plate is precisely designed through digital methods, and then guides the tooth preparation step by step, without the problem of insufficient or excessive preparation, and can reduce the difficulty of operation for clinicians, improve the quality of clinical restoration and patient satisfaction, and is accurate A beneficial attempt of medical concepts in the field of dental restoration.

Description

technical field [0001] The invention relates to a personalized step-by-step indication guide plate for anterior teeth veneer preparation, in particular to a personalized anterior tooth porcelain that can assist stomatologists in the process of precise porcelain veneer tooth body preparation in the process of aesthetic restoration of anterior teeth veneers Preparation method and application of veneer preparation guide. Background technique [0002] In recent years, with the improvement of people's quality of life, all-ceramic veneer restoration has been favored by more and more patients and oral clinicians due to its high success rate and good long-term restoration effect, and has become an anterior interdental gap. , Dental fluorosis, tetracycline teeth, deformed small teeth and other treatment methods. However, although the concept of diagnostic veneers has been put forward in recent years, patients can intuitively feel the general effect of dental veneers in the mouth, an...
