Filter by:This retrospective study aims to value the bone loss and the success and survival of the dental implants produced by additive manufacturing installed in an area grafted with Plenum® Osshp (synthetic bone graft). In addition, the biological and biomechanical performance of implant restorations supported through an observational retrospective solution will be observed. From 50 to 100 survey participants will be selected, who will be invited to attend the clinic for clinical, radiographic, and prosthetic evaluation and successful parameters between baseline, 3, 6, and 12 months. The data obtained regarding bone loss (primary outcome) of the analyzed regions and implant success and survival in area grafted with Plenum® Osshp (secondary outcome) will be evaluated by the paired t-test for the evaluation of the times (3, 6, and 12 months) and survival curves of the installed dental implants.
The aim of this study is to qualitatively and quantitatively evaluate bone neoformation in maxillary sinus lift surgery filled with Plenum® Oss hp, compared to filling with autogenous bone, and to verify the association of Plenum® Osshp with i-PRF (i-PR - injectable platelet-rich fibrin). For this, forty (40) participants will be recruited, divided into 4 groups, which will have 10 participants each, namely: Group 1: Autogenous bone; Group 2: Plenum® Osshp; Group 3: Plenum® Osshp; + i-PRF and Group 4: Plenum® Osshp; + autogenous bone. To evaluate the primary outcome, volumetric analysis will be performed by obtaining computed tomography scans at 15 days (T1) and 6 months (T2) after graft surgery, with the aid of a volumetric tomography machine for dentofacial images. The values obtained at T2 will be subtracted from those obtained from T1 to obtain the volumetric stability value. After six months of repair, biopsies will be performed using a trephine drill, followed by the installation of implants and healers. Through microcomputed tomography analysis, the parameters of bone volume fraction (BV/TV), total porosity (Po.Tot), trabecular thickness (Tb.Th), number of trabeculae (Tb.N) and separation of trabeculae (Tb.Sp) will be evaluated. Histomorphometric analysis will be performed to obtain the areas of bone neoformation, connective tissue and remaining biomaterial that will be calculated for each area of the sample (cervical, intermediate, and apical) and later summed, obtaining the total representative area of the sample. Through immunohistochemical analysis, specific primary antibodies to Runx2, VEGF, Osteocalcin (OC) and Tartrate-Resistant Acid Phosphatase (TRAP) will be identified. The occurrence of adverse events will be collected through the analysis of pain, infection, and edema. The quantitative results of the histomorphometric, microtomographic, and volumetric stability analysis will be tabulated and submitted to the ANOVA test, and if they present a statistically significant difference, it will be followed by the Tukey test (post hoc). A significance level of p<0.05 will be adopted for all tests.
Currently, an ongoing generational shift of the dental community in Sweden originates from an increased number of retiring dentists. Meanwhile, a declining number of dental professionals puts a strain on the care system and reduces the availability of dental care to patients in need of treatment. With fewer experienced dentists, available to guide newly graduated dentists, an increased number of referrals to specialist care units might be a consequence. E.g. referrals to oral and maxillofacial departments originating from a need of assistance in more advanced cases of assessments, treatment planning and therapies. The decreasing number of dentists is also possible to negatively affect the recruitment to specialized dental units, which in turn further decreases treatment availability. When the need for dental care exceeds the capacity of the dental care providers, a possible solution might be to minimize the number of referrals possible to treat in general dentistry, thus prioritize patients truly in need of specialist care. Hence, a reduced waiting time and improved accessibility to an adequate treatment. The aim of this study is to explore the suitability of referrals concerning exodontia to the departments of oral and maxillofacial surgery in southern Sweden. The primary objective is to assess the level of difficulty in referrals on dental extractions. Secondary objectives are assessments of outcome from treatment and comparison of the suggested treatment of the referral with the outcome. The hypothesis is that the level of difficulty of the required treatments in referrals to oral and maxillofacial departments in southern Sweden is low and constitutes a contributing factor to prolonged waiting queues in specialized dentistry.
The aim of the present project is to evaluate the outcome from reconstruction of the jaws, with a standardized simplified technique, after a continuous defect. The primary objective is to measure recurrence of the tumour is present as a marking for insufficient resection margins. Secondary objectives are measures of survival of transplanted tissues, registered complications at follow-up and measures of healing between segments of transplanted bone (bone bridging).
Aims: To investigate the incidence of bleeding complications during oral surgical procedures in patients medicated with DOACs. To investigate the perioperative and postoperative bleeding volume during oral surgical procedures in patients medicated with DOACs. To examine whether increased perioperative bleeding volume complicates the planned intervention, thereby prolonging the operation time. Previous studies have shown that the incidence of healthcare-consuming bleeding complications following oral surgical procedures in patients who are prescribed warfarin is approximately 4% (9). To investigate whether the incidence is higher or lower by the intake of DOAC it is considered to be sufficient with 100 patients in each group. The groups consist of patients who are prescribed warfarin, DOACs, as well as a control group. Hypothetical outcomes: The incidence of bleeding complications and the perioperative and postoperative bleeding volume during oral surgical procedures in patients medicated with DOACs are higher compared to patients medicated with warfarin and patients taking no anticoagulants. Increased perioperative bleeding volume complicates the planned intervention, thereby prolonging the operation time. Clinical relevance: The study will serve as a basis for the development of treatment guidelines for patients who medicate with DOACs. If it turns out that the oral surgery procedure presents no increased risk of complications and that the bleeding volume does not complicate the surgery significantly, it may be recommended that patients who medicate with DOACs whom are in need of oral surgical procedures seek ordinary dental care.
Periodontal disease is a gum infection caused by plaque on teeth containing both bacteria and calculus (hard) deposits. These need to be removed on a regular basis to maintain gum health and to prevent teeth weakening. A routine cleaning procedure, scaling/root planing, is accompanied with post-operative soft tissue tenderness and teeth sensitivity making oral hygiene maintenance difficult during wound healing. The need for novel therapeutic approaches, such as cyanoacrylate adhesives, has been identified. It has been hypothesized that its application may provide comfort and assist patients with their daily oral self-care procedures following teeth cleaning.
The final stage of any surgical procedure is suturing. Sutures have a vital rule in wound healing- they are responsible for flaps approximation, hemostasis and restoring function and esthetics. Choosing the right suture is crucial especially in oral sites because of its unique anatomical features: the presence of saliva and the patient's everyday function- swallowing, talking, eating etc. Sutures require certain physical properties such as tensile strength, dimensional stability, lack of memory, knot security and elasticity. One highly important quality is the ability to prevent or reduce bacterial adhesion and by that to prevent secondary infection. There are many kinds of sutures in the market- none of which contains all the ideal features. The aim of the study is to compare the amount of bacterial adhesion to different kinds of sutures in patients undergoing periodontal surgery.
The purpose of this pilot study is to determine if Topical Oral Wound Emulsion (TOWE) assists with dental wound healing and relieves pain from oral wounds.
Whether patient-maintained sedation (the patient controls his/her degree of sedation using a hand-held device) using the drug propofol is safer and more effective when using deteriorating reaction time as an added safeguard against the potential for over sedation in a groups of patients undergoing oral surgery, general dentistry and colonoscopy.
