Periodontal Disease and Nonsurgical Periodontal Therapy on the OHRQoL of the Patient: A Pilot Study of Case Series.

The objective of this prospective study was to assess oral health-related quality of life (OHR-QoL) in patients with periodontitis and nonsurgical periodontal treatment. A prospective, longitudinal case series study was carried out at the University Dental Clinic of the Morales Meseguer Hospital in Murcia. Eighty periodontal patients with periodontitis, aged 22 to 72 years, were included in this study.

Electrical Potentiometry with Intraoral Applications.

Dental implants currently in use are mainly made of titanium or titanium alloys. As these metallic elements are immersed in an electrolytic medium, galvanic currents are produced between them or with other metals present in the mouth. These bimetallic currents have three potentially harmful effects on the patient: micro-discharges, corrosion, and finally, the dispersion of metal ions or their oxides, all of which have been extensively demonstrated in vitro.

Ozone in Patients with Periodontitis: A Clinical and Microbiological Study.

The purpose of this article was to assess the effectiveness of ozone therapy as an adjunct to mechanical therapy in periodontitis patients. Thirty-two patients diagnosed with generalized periodontitis were selected, with a total of 655 teeth examined. Each patient’s mouth was divided into four quadrants (the split-mouth model) to be randomly treated with four sessions of gaseous ozone or air.

Primary stability and PES/WES evaluation for immediate implants in the aesthetic zone: a pilot clinical double-blind randomized study.

The use of immediate implants in the aesthetic area is a technique widely used in modern implantology. The characteristics of the patient, the implant, and the surgical procedure used may influence the final results. The aim was to assess whether the implant design affects primary (P.

Clinical and Surgical Outcomes in Extensive Scalp Reconstruction after Oncologic Resection: A Comparison of Anterolateral Thigh, Latissimus Dorsi and Omental Free Flaps.

Microsurgical scalp reconstruction is indicated in patients with large scalp defects. The aim of this study was to compare the outcomes of scalp reconstruction in oncologic patients reconstructed with latissimus dorsi (LD), anterolateral thigh (ALT), and omental (OM) free flaps. Thirty oncologic patients underwent scalp reconstruction with LD (10), ALT (11), and OM (9) flaps.

Vertical Ridge Augmentation of Fibula Flap in Mandibular Reconstruction: A Comparison between Vertical Distraction, Double-Barrel Flap and Iliac Crest Graft.

Double-barrel flap, vertical distraction and iliac crest graft are used to reconstruct the vertical height of the fibula. Twenty-four patients with fibula flap were reconstructed comparing these techniques (eight patients in each group) in terms of height of bone, bone resorption, implant success rate and the effects of radiotherapy. The increase in vertical bone with vertical distraction, double-barrel flap and iliac crest was 12.

Primary Maxillary Reconstruction With Fibula Flap and Dental Implants: A Comparative Study Between Virtual Surgical Planning and Standard Surgery in Class IIC Defects.

Purpose: Oncological patients who undergo bilateral subtotal maxillectomies develop functional and esthetic sequelae that require immediate reconstruction. The purpose of this study is to evaluate the primary reconstruction of maxillary defects with fibula flap and dental implants assisted by virtual surgical planning (VSP) and to assess the postoperative outcomes compared with standard surgery.

Material And Methods: A retrospective study was designed between January 2016 and April 2020 with 12 oncologic patients who underwent subtotal bilateral maxillectomy.

Control of Peri-Implant Mucous Inflammation by Using Chlorhexidine or Ultraviolet C Radiation for Cleaning Healing Abutments. Double-Blind Randomized Clinical Trial.

Two-phase implants must be exposed to the external environment after the period of osteointegration has elapsed. For this purpose, a healing abutment is placed passing through the mucosa while forming the emergence profile. The continuous connection and disconnection can lead to an alteration in the tissue maturation, both because of the contact of bacterial plaque and because of the mechanical trauma that involves its manipulation, manifesting with different degrees of erythema or bleeding.

Effects of Ultraviolet Photoactivation on Osseointegration of Commercial Pure Titanium Dental Implant After 8 Weeks in a Rabbit Model.

This study investigated whether a 6-Watt ultraviolet C-lamp was capable of producing photofunctionalization on commercial implants during a medium observation term of 8 weeks. A total of 20 implants were inserted in 5 New Zealand rabbits, with each animal receiving 2 implants per tibia (one photofunctionalized and one untreated), according to a previously established randomization sequence. All implants were inserted by a single surgeon following the manufacturer's instructions.

Effect of Rotary Instrument Mineral Oil Lubricant on Osseointegration: A Randomized, Blinded Study in Rabbits.

The mechanisms of early failures in dental implant osseointegration are unclear. A possible cause of low levels of bone formation is lubricant contamination on implants during insertion. To explore the impact of lubricant contamination on dental implants, we used 5 New Zealand rabbits and inserted 2 implants per tibia in each animal for a total of 4 implants per animal (20 implants in total).

Effects of the Preoperative Administration of Dexketoprofen Trometamol on Pain and Swelling After Implant Surgery: A Randomized, Double-Blind Controlled Trial.

The fear of postoperative pain is often mentioned by patients as one of the factors that is most frequently associated with dental implants. To reduce this factor, a single oral dose of 25 mg dexketoprofen trometamol (DKT) or placebo was administered 15 minutes before implant surgery. One hundred patients who required single-implant treatments were randomly assigned to 1 of 2 blinded groups.

Cone-Beam CT Assessment of the Position of the Medial Lingual Foramen for Dental Implant Placement in the Anterior Symphysis.

Objectives: To determine the position of the mandibular medial lingual foramen with cone-beam CT (CBCT) 3D imaging modalities when implants are to be placed in the anterior symphysis of the mandible.

Materials And Methods: A total of 111 CBCTs were considered acceptable and analyzed. The variables measured were as follows: (1) length of the outlet duct; (2) distance from the canal to the buccal cortex; (3) distance from the canal to the inferior cortex; (4) distance from the canal to the lingual cortex; (5) distance from the canal to the alveoli of the nearest tooth in dentate patients and distance from the canal to the marginal crest in edentulous patients; (6) angle of the duct to the horizontal Frankfurt plane; (7) diameter of the exit orifice; and (8) output level of the socket in relation to the teeth and the presence of bifurcations.

Zirconia implants and peek restorations for the replacement of upper molars.

Background: One of the disadvantages of the zirconia implants is the lack of elasticity, which is increased with the use of ceramic or zirconia crowns. The consequences that could result from this lack of elasticity have led to the search for new materials with improved mechanical properties.

Case Presentation: A patient who is a 45-year-old woman, non-smoker and has no medical record of interest with a longitudinal fracture in the palatal root of molar tooth 1.

The aim of this study was to assess the presence of aspartate aminotransferase (AST) in peri-implant crevicular fluid, with or without clinical signs of mucositis, to determine its predictive diagnostic value, sensitivity, and specificity. The AST levels were determined (at a threshold of 1200 µIU/mL) for 60 clinically successful implants in 25 patients with or without peri-implant mucositis. Samples were taken prior (AST1) to peri-implant probing with a manual constant-pressure probe (0.

Neuropathic orofacial pain after dental implant placement: review of the literature and case report.

Persistent and chronic pain is more common in the head and neck region than in any other part of the body; therefore, dentists are more likely to encounter these rather complex cases in their practices. In this report, we present a brief review of neuropathic orofacial pain (NOP) that can begin after deafferentation of trigeminal nerve fibers after root canal treatment, apicoectomy, tooth extraction, or implant placement or idiopathically. A case of NOP occurring after a surgical implant procedure in a 62-year-old woman is presented.

Etiology, risk factors and management of implant fractures.

Implant fracture is an infrequent and late biomechanical complication with a serious clinical outcome. In effect, such fractures pose important problems for both the patient and the dental surgeon. According to most literature sources, the prevalence of dental implant fractures is very low (approximately 2 fractures per 1000 implants in the mouth).

Periodontal disease affecting tooth furcations. A review of the treatments available.

The molars are the teeth that suffer the greatest periodontal destruction in untreated patients. When periodontal disease affects the furcation of a tooth, the chance that it will be lost increases considerably. An increase in the exposed root surface, anatomical peculiarities and irregularities of the furcation surface all favor the growth of bacteria.

Tobacco as a risk factor for survival of dental implants.

Background: It has been shown that smoking habits represent an increased risk for impaired bone healing and implant failure. This study aimed to evaluate the implant survival rates among non-smokers (NS) and different kinds of smokers (S).

Methods: A retrospective analysis was made over a 5-year period of the clinical and radiographic findings corresponding to 66 consecutive patients who had received a total of 165 dental implants.

Necrotising periodontal diseases.

Necrotizing gingivitis (NG) or necrotising ulcerative gingivitis (NUG) is considered to be an acute opportunistic gingival infection caused by bacterial plaque. It appears more frequently in undernurished children and young adults as well as patients with immunodeficiency. In its pathogenesis, there are factors related to the oral microbiota with invasion processes on the one hand, and on the other hand, factors associated with the host, such as signs of capillary and immunological disorders as well as undernurishment.
