В статье представлены результаты анализа возможных вариантов хирургического этапа реабилитации пациентов с частичным вторичным отсутствием зубов в условиях дефицита костной ткани альвеолярного отростка/части челюсти в период с 2008 по 2017 г. (n=1004). Выделены три основных варианта хирургической реабилитации: поэтапный подход, включающий проведение костно-реконструктивной операции, последующее проведение дентальной имплантации (n=562); дентальная имплантация с одномоментным проведением костно-реконструктивной операции (n=362); установка «узких/ коротких» дентальных имплантатов (n=80). Приведены данные по частоте встречаемости интра-и послеоперационных осложнений до этапа протезирования. За прошедший период отмечена тенденция к сокращению количества операций по поэтапному подходу, с увеличением количества одномоментно проводимых операций и операций по установке «узких/ коротких» имплантатов. Ключевые слова: костно-реконструктивные операции, «узкие» и «короткие» имплантаты, ограниченный объем костной ткани.
The article presents the results of the analysis of the success of treatment and survival of dental implants in the treatment of patients with bone deficiency in the framework of multi-stage and single-stage approaches for bone grafting operations using standard-sized dental implants and in the framework of the approach using narrow/short dental implants without bone augmentation surgery. Based on the results obtained, the degree of expediency (p0.05) of choosing an approach to treatment can be selected depending on the type, location of the defect and the number of missing teeth.
Relevance. Tooth extraction is the most common operation in oral surgery practice. For oroantral communication (OAC) treatment and prevention as one of the surgery complications, it is paramount to study the prevalence of anatomical risk factors for OAC in patients based on their facial sk eleton type.Materials and Methods. We analyzed 1629 cone-beam CT scans of patients aged 18 to 85 years of both sexes to determine the potential risk of OAC in patients with different types of the facial skeleton.Results. The overall assessment of OAC potential risk demonstrated a high risk in 29.7% of cases (4514 teeth) (p < 0.01). The high-risk group determined teeth most often in patients with a mesoprosopic type of facial skeleton – 31.2% of cases (2912 teeth), in euryprosopic – 29.46% (914 teeth), in leptoprosopic – 24.96% of cases, (688 teeth), (p < 0.01). The potential risk of the first and second molar OAC was the highest of all teeth in all facial skeleton types (p < 0.01).Conclusion. A potentially high OAC risk of about 30% can be related to the upper teeth, located in the maxillary sinus floor area in patients with any facial skeleton type, though the risk is higher in meso- and euryprosopic types (p < 0.01). Among all groups of teeth, the highest potential risk of OAC (up to 40%, p < 0.01) is in the maxillary 1st and 2nd molar region in any facial sk eleton type.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
