Primary and Secondary Elevations of Maxillary Sinuses: a Prospective Clinical Study in the Posterior Maxillary Region
China40 participantsStarted 2024-04-07
Plain-language summary
About 40 people will participate in the study, which will be conducted at Southern Medical University Southern Hospital. All subjects need to sign an informed consent form before screening, and successful subjects can enter the study. Experimental and control subjects were treated according to the protocol. Treatment was held until the participant entered a follow-up period, or until any of the withdrawal criteria were met. According to conventional clinical practice, the study needs to evaluate the patient's subjective perception and soft and hard tissue changes at 3 months, 6 months, and 1 year after successful implant placement. The specific process is divided into: 1. Screening period: All subjects need to complete the relevant examinations of the screening period before enrollment, and screen according to the admission criteria. (1) Sign informed consent; (2) Record demographic data: date of birth, gender, initials; (3) Medical history and physical examination: collection includes understanding of any current or past diseases, medications, drug allergy history, surgical history, radiotherapy and chemotherapy history, ethnic background, smoking history, whether alcoholism, oral hygiene habits and oral examination, etc.; (4) Among them, oral examination includes the whole oral health before and after surgery and oral and maxillofacial CBCT imaging examination; 2. Treatment period: the control group underwent transalveolar crest parietal maxillary sinus floor lift immediately after implants; The experimental group underwent implant implantation after 6 months of transalveolar crest parietal maxillary sinus floor lift. 3. Follow-up period: The study needs to evaluate the subjective feelings and soft and hard tissue changes of patients at 3 months, 6 months and 1 year after implant placement.
