Surgeons' Prediction of Dental Surgery Complications and the Influence of Patient Characteristics: Development of an AI Model

The goal of this observational study is to learn how to better predict and prevent intra- and postoperative complications in oral surgery in adult patients referred for oral surgical procedures. The study aims to understand how accurately surgeons can foresee complications and which patient, tooth, and surgery related factors influence the outcomes. The research questions are: * What is the incidence of intra and postoperative complications in oral surgery? * Which factors predict these complications, and how accurately can surgeons anticipate them? * Can the development of an AI tool reduce postoperative complications? Participants will: * Receive standard oral surgery treatment at a private referral clinic (Specialtandlægerne Sjælland). * Have clinical information collected about their procedure, medical history, and personal characteristics (including anxiety level). * Conduct a short questionnaire, the STAI-6 and the I-PANAS-SF. * Have the surgeon record their prediction of whether complications are expected. * Be followed in the postoperative lapse to document whether complications occur after surgery.

The Effect Of Enamel Matrix Derivatives On Gingival Tissue Thickness

Scientists do research to answer important questions which might help change or improve the way we do things in the future. The investigators know that using Enamel Matrix Derivatives results in thicker gum tissues around teeth. This study will test to see if using EMD around implants results in thicker gum tissues around implants.

Accuracy, Stability and Safety of Orthodontic Mini-implant Template in the Infrazygomatic Crest Zone

The goal of this clinical trial is to learn accuracy, stability and safety of orthodontic mini-implant template in the infrazygomatic crest zone.References population isOrthodontics patients which is require to implant miniscrew as anchorage requirement .Inclusion criteria 1. The orthodontic clinical design should include the use of miniscrews for anchorage requirements in maxillary arch. 2. Age of 18-35 years old 3. Patients must have no prior history of orthodontic treatment and must have a healthy periodontal condition or no history of trauma before the current orthodontic treatment. Exclusion criteria 1. Patient with poor oral hygiene, history of systemic diseases and metal allergies; 2. Patients with osteoporosis and inability to retain the TAD; 3. Patients who require orthognathic surgery for severe skeletal malocclusion; 4. Smoking patients which will affect the success rate of the implant placement 5. Patients with incomplete medical records. The main questions it aims to answer are: The general objective of this research is to study the effect of utilizing modified miniscrew template as tools for the miniscrew placement. Specific Objective The specific objectives for this study will be: 1. To compare the accuracy of miniscrews implanted using modified template by computer-aided design and without template guide (conventional method). 2. To compare the stability of miniscrews implanted using modified template by computer-aided design and without templete guide (conventional method). 3. To compare the safety of miniscrews implanted using modified template by computer-aided design and without templete guide (conventional method). Participants will: 1. The patient undergoes routine pre-orthodontic examination, model analysis, cephalometric measurement, and develops an orthodontic treatment plan. 2. .The patient undergoes routine pre-orthodontic examination, model analysis, cephalometric measurement, and develops an orthodontic treatment plan. 3. The process of insertion of miniscrew will be depend on the group either Intervention Group or Control Group. The guide plate will be used for miniscrew insertion in Intervention Group and experience based on the patient's digital films for Control Group. The area of insertion of the miniscew will be the upper alveolar ridge between premolars and molar tooth. The procedure will be performed under local injection anesthesia. 4. The process of implanting implant nails on Intervention Group is as follows: the material and model of the implanted micro implant nails are exactly the same as those of the traditional positioning set. The implant nail diameter is 2mm and the length is 10 mm. The implant surgery was performed by the same orthodontist in accordance with recommended operating procedures. Preoperative local anesthesia will be performed, and micro-implant nails will be implanted at the intended implantation site under the guidance of the guide plate. The area of implantation is maxillary zygomatic alveolar ridge. 5）The process of implanting implant nails on the Control Group is as follows: Similar to the intervention group, but the doctor implant the miniscrew based on experience with CBCT scans. 6\) Collect date before and after implant nail implantation.The digital plaster models will be obtained by scanning with a D700 scanner (3shape, Denmark). Both digital models and CBCT scan data will be imported into Segma implant guide software (Beijing, China). The combination method is as follows: first, open the file in a way that only uses CBCT for implant design and adjust the density of anatomical landmarks such as the maxillary sinus, condylar foramen, or protrusions to an explicit level. Then, the teeth or jaw landmark points of the model and CBCT will be selected to reconstruct a 3D model. 4）The data collection will be performed by obtaining plaster model using intaoral scanner at T1(immediate post insertion) and T2 (6 months post insertion)

Vibropneumostimulation in the Rehabilitation After Dental Implantation

A new comprehensive technique of dental implantation and rehabilitation of patients will be developed and theoretically justified, including an individual dental implant of a dowel system made of non-woven titanium material with through porosity and vibropneumostimulation, which will improve the functional and anatomical results of treatment. In the complex treatment and rehabilitation of patients after dental implantation, a vibropneumostimulator with vibratodes of its own design will be used, which activate bone remodeling, which will expand the practical application and theoretical knowledge in the field of hardware massage.

The Application of Root Analogy Implant in Immediate Implantation

The current clinical implant techniques used include immediate implantation, early implantation, and delayed implantation. With the acceleration of the current pace of life, immediate implantation is increasingly favored by patients due to its advantages such as fewer surgeries, shorter waiting times, and less impact on aesthetics. The research group has shown that the mismatch between traditional implants and extraction sockets in immediate implantation surgery has caused some complications. Therefore, it is believed that 3D printed personalized root shaped implants with certain roughness are more suitable for use in immediate implantation surgery.

Immediate Implant Placement in the Posterior Region Combining Sealing Socket Abutment and Peri-implant Socket Filling.

The primary endpoint of this study is to compare the soft tissue contour changes after immediate implant placement combined to peri-implant socket filling with a sealing socket abutment (SSA) versus a standard healing abutment. The hypothesis is that the SSA better preserves the alveolar ridge profile in the cervical region compared to a conventional healing abutment. The secondary objectives aim to evaluate 3D hard tissue changes, peri-implant bone remodeling, soft tissue health, esthetic outcomes and the patients related outcome measures.
