Materials And Methods: Stability of dental implants with two different types of surface treatments was compared utilizing resonance frequency analysis (RFA).

Flapless Guided Dental Implant Surgery in a Systemically Compromised Patient: A Case Report.

The use of surgical guides in implant treatment offers several advantages, including reduced surgery time, flapless procedures, and enhanced precision and reliability in implant placement. By utilizing tomography and scanning technologies, a patient's complete anatomical structure can be transferred into software in three spatial planes. This allows for the three-dimensional printing of surgical guides that ensure the accurate execution of the procedure.

Background: To verify the influence of macrogeometry with healing chambers on the osseointegration of dental implants by analyzing implant stability quotient (ISQ) and evaluate the correlation between insertion torque and ISQ insertion with different macrogeometries.

Methods: In total, 26 implants were installed in the posterior mandible of eight patients with sufficient bone height for the installation of implants measuring 3.5 mm in diameter and 9.

Viability and collagen secretion by fibroblasts on titanium surfaces with different acid-etching protocols.

Background: From the consolidation of surface treatments of dental implants and knowledge on the cellular mechanisms of osseointegration, studies have highlighted the importance of a connective tissue seal against the implant to prevent contamination from the oral environment and consequent biofilm formation.

Objective: This in vitro study aimed to evaluate whether different titanium surface treatments using acid solutions promoted an increase in collagen secretion, proliferation, and viability of fibroblasts.

Material And Methods: Commercially pure grade-4 titanium disks (6 × 2 mm) were treated with different acid solutions (hydrochloric, nitric, and sulfuric) for 20 and 60 min, respectively, obtaining mean surface roughness of 0.

Rehabilitation of a Severely Resorbed Posterior Mandible with 4-mm Extra-Short Implants and Guided Bone Regeneration: Case Report with 3-year Follow-up.

Alveolar bone resorption has been a major challenge for implant placement in regions limited by anatomical structures. New alternatives have been introduced with the inclusion of extra-short implants in dentistry. The association of guided bone regeneration (GBR) with the use of extra-short implants might be a viable alternative for regions with limited bone height.

Predicting Pain After Tooth Extraction: Pain Prediction Index.

Aims: To identify relevant variables that may predict pain after routine extraction of erupted teeth, to construct a Pain Prediction Index (PPI) based on these variables, and to verify how these variables are related by using valid structural equation modeling (ie, path analysis).

Methods: This study was designed as an observational prospective study for postoperative memory of pain after dental extraction of erupted teeth. Data from a total of 781 surgical procedures related to dental extractions were included.

Impact of Dentofacial Deformity on Quality of Life: Age and Gender Differences Evaluated Through OQLQ, OHIP and SF36.

Objectives: The aim of this study was to verify the impact of dentofacial deformity on quality of life and explore gender and age differences.

Material And Methods: The impact of dentofacial deformity (DD) on quality of life was evaluated through questionnaires; Short Form Health Survey (SF36), Oral Health Impact Profile Questionnaire (OHIP), Orthognathic Quality of Life Questionnaire (OQLQ) and a single question answered by a Visual Analogue Scale.

Results: Significant differences between male and female patients were observed in domains of OQLQ (oral function, P = 0.

Comparative, Histological and Histomorphometric Analysis of Three Anorganic Bovine Xenogenous Bone Substitutes: Bio-Oss, Bone-Fill and Gen-Ox Anorganic.

Introduction: Anorganic bovine xenogenous grafts show the best performance as bone substitutes in implantodontics. Bio-Oss is the world's most widely used and investigated anorganic bone substitute. This article compares two anorganic bovine bone substitutes (Bone-Fill and Gen-Ox anorganic) with Bio-Oss.

Clinical evaluation of anodized surface implants submitted to a counter torque of 25 ncm after 60 days of osseointegration: study in humans.

Introduction: Decreasing the time needed for osseointegration has always been a big challenge for modern implantodontics. The main factor which helps to decrease the time needed for osseointegration is the newly developed surfaces being used, as well as their microstructures, in relation to their osseoinductive properties. The aim of this work is to clinically evaluate the osseointegration of the implants when using The anodized surfaces in humans, following a 60 days-period of osseointegration.

Comparative study of immediately inserted dental implants in sinus lift: 24 months of follow-up.

Objectives: The primary aim of this study is to evaluate the success rate of immediately inserted dental implants in sinus lift and the secondary aim is to assess the reliability of performing simultaneous surgery for sinus lift, grafting and implant placement in situations of very low residual bone heights (<4 mm) in the posterior maxillae.

Materials And Methods: A series of consecutive patients who sought dental implant rehabilitation were included in this study. The sinus lift cases were selected and divided into two groups based on the maxillary alveolar height, ≥4 mm of radiographically measurable bone height (Group 1) and < 4 mm of bone height (Group 2).

A single dose of amoxicillin and dexamethasone for prevention of postoperative complications in third molar surgery: a randomized, double-blind, placebo controlled clinical trial.

Background: The aim of this study was to assess the efficacy of a single prophylactic dose of amoxicillin and/or dexamethasone in preventing postoperative complications (PC) after a surgical removal of a single mandibular third molar (M3).

Methods: This study is a randomized, placebo controlled clinical trial. Four groups were included: Group 1 (G1) included a prophylactic dose of 2 g of amoxicillin and 8 mg of dexamethasone; Group 2 (G2) included a prophylactic dose of 2 g of amoxicillin and 8 mg of placebo; Group 3 (G3) included a prophylactic dose of 8 mg of dexamethasone and 2 g of placebo and; Group 4 (G4) placebo.

Glucose levels and hemodynamic changes in patients submitted to routine dental treatment with and without local anesthesia.

Objective: The aim of this study was to (1) observe the extent to which hemodynamic and glucose measurements change in patients submitted to a dental procedure with and without a local anesthetic and a vasoconstrictor (LAVA; 2% mepivacaine with adrenaline 1100,000) and (2) correlate those parameters with the patients' anxiety levels.
