Relationship between preoperative anxiety and postoperative satisfaction in dental implant surgery with intravenous conscious sedation
2008
Purpose: To study if patient preoperative anxiety is related to age and gender and to compare preoperative anxiety with postoperative patient and surgeon satisfaction in dental implant surgery under intravenous conscious sedation. Materials and Methods: Dental implants were placed in 102 patients under local anesthesia and intravenous conscious sedation. The procedures were performed with or without dental extractions, and with or without bone regeneration. Anxiety was evaluated using Corah?s Dental Anxiety Scale and levels of surgeon and patient satisfaction were evaluated on an adapted scale. Results: Low preoperative anxiety was observed in 27.8% of patients, moderate in 50%, and high in…
How could multimedia information about dental implant surgery effects patients- anxiety level?
2017
Background To evaluate the effects of different patient education techniques on patients’ anxiety levels before and after dental implant surgery. Material and Methods Sixty patients were randomized into three groups; each contained 20 patients; [group 1, basic information given verbally, with details of operation and recovery; group 2 (study group), basic information given verbally with details of operative procedures and recovery, and by watching a movie on single implant surgery]; and a control group [basic information given verbally “but it was devoid of the details of the operative procedures and recovery”]. Anxiety levels were assessed using the Spielberger’s State-Trait Anxiety Invent…
Guided implant surgery with modification of the technique involving the raising of a semicircular miniflap: a preliminary study.
2010
Objective: An evaluation is made of pain, swelling and peri-implant attached mucosal width after implant-based rehabilitation involving guided surgery and a modification of the technique with the raising of a semicircular miniflap, in single and partial replacements. Study design: A case-control study was carried out. The study group consisted of 12 patients with the placement of 19 implants using a guided surgery and miniflap technique. The control group consisted of 12 patients with the placement of 22 implants using the conventional technique. Each patient scored postoperative swelling and pain by means of a visual analog scale (VAS). Attached vestibular mucosa width was evaluated 12 wee…
Technical Note: Minimal Access Surgery for Cochlear Implantation with MED-EL Devices
2005
<i>Background:</i> Minimally invasive techniques have been described for cochlear implant surgery, but so far this had not been the case for Med-EL devices. <i>Objective:</i> To describe a newly developed minimal access approach for the implantation of Med-EL devices and report our results after up to 1 year of follow-up in 52 patients. <i>Discussion:</i> The use of a minimally invasive approach without raising a flap or extensive drilling of a bony well was feasible in all 52 patients of this series. It shortened the surgical time to an average of 45 min and there were no specific postoperative complications. The average follow-up of 8.4 months was uneve…
Alternative surgical management of oroantral fistula using auricular cartilage
2015
One of the clinical complications encountered by oral and maxillofacial surgeons is oroantral communication (OAC) with subsequent formation of oroantral fistula (OAF). Many techniques and treatment modalities have been described for the management of OAC and OAF. There are advantages and disadvantages of all these techniques. We report a 21-year-old male patient who was admitted to our department for the presence of an OAF and was treated using an auricular cartilage graft. This technique may be useful to treat OAF and to provide a solid alveolar bone site for subsequent pre-implant surgery. Key words:Auricular cartilage, implant surgery, oroantral fistula.
Accuracy and the role of experience in dynamic computer guided dental implant surgery: an in-vitro study
2019
Background To compare the accuracy of implant placement using the conventional freehand method and a dynamic navigation system; to assess the role of the surgeon’s experience in implant placement using these two methods. Material and Methods A randomized in-vitrostudy was conducted. Six resin mandible models and 36 implants were used. Two researchers with differing clinical experience (novice and experienced) placed implants using either the Navident dynamic navigation system (navigation group) or the conventional freehand method (freehand group). Accuracy was measured by overlaying the real position in the postoperative CBCT on the virtual presurgical placement of the implant in a CBCT ima…
Effects of minute misregistrations of prefabricated markers for image-guided dental implant surgery: an analytical evaluation
2012
Objectives The goal of the present study was to develop a theoretical analysis of errors in implant position, which can occur owing to minute registration errors of a reference marker in a cone beam computed tomography volume when inserting an implant with a surgical stent. Material and methods A virtual dental-arch model was created using anatomic data derived from the literature. Basic trigonometry was used to compute effects of defined minute registration errors of only voxel size. The errors occurring at the implant's neck and apex both in horizontal as in vertical direction were computed for mean ±95%-confidence intervals of jaw width and length and typical implant lengths (8, 10 and 1…
STN area detection using K-NN classifiers for MER recordings in Parkinson patients during neurostimulator implant surgery
2016
Deep Brain Stimulation (DBS) applies electric pulses into the subthalamic nucleus (STN) improving tremor and other symptoms associated to Parkinson's disease. Accurate STN detection for proper location and implant of the stimulating electrodes is a complex task and surgeons are not always certain about final location. Signals from the STN acquired during DBS surgery are obtained with microelectrodes, having specific characteristics differing from other brain areas. Using supervised learning, a trained model based on previous microelectrode recordings (MER) can be obtained, being able to successfully classify the STN area for new MER signals. The K Nearest Neighbours (K-NN) algorithm has bee…
Survival rate of odontogenic descending necrotizing mediastinitis. Our experience in last 5 years
2022
Descending necrotising mediastinitis is one of the most lethal and least frequent forms of mediastinitis. It is a life-threatening infection most frequently originating from an oropharyngeal or odontogenic infection. A retrospective study of 6 patients diagnosed and treated for descending necrotising mediastinitis between 2015 and 2020 is reported. All patients were male, mean age of 34.83 years; 66% were smokers. 83% had an orocervical infection and 34% had initial mediastinal spread. All patients were treated initially with empirical broad-spectrum antibiotics and surgical drainage, with subsequent admission to the Intensive Care Unit; only one of them required tracheostomy. The mean hosp…
Evaluation of effectiveness of photobiostimulation in alleviating side effects after dental implant surgery. A randomized clinical trial
2020
Background To assess if photobiostimulation (PBS) alleviates pain intensity/duration and swelling after implant surgery. Material and Methods Sixty subjects (27 male and 33 female, with a mean age of 47,13 8.05 years) were included and randomly assigned to experimental group (implant surgery and photobiostimulation), placebo group (implant surgery and simulated photobiostimulation) and control group (implant surgery only). Inclusion criteria: subjects older than 20 years, with a healthy oral mucosa and requiring implant surgery. Exclusion criteria: pregnancy, history of implant failure, light sensitivity, metabolic deseases, consumption of antibiotics or corticosteroids in the last two week…
