COVID-19 and Its Repercussions on Oral Health: A Review.

In 2019, a new type of coronavirus, SARS-CoV-2, the causing agent of COVID-19, was first detected in Wuhan, China. On 11 March 2020, the World Health Organization declared a pandemic. The manifestations of COVID-19 are mostly age-dependent and potentially more severe in cases with involved co-morbidities.

Internal Hexagon vs Conical Implant-Abutment Connections: Evaluation of 3-Year Postloading Outcomes.

Different types of internal implant-abutment connections, namely hexagon and conical, have been used for implant restoration. However, data regarding the benefits of these internal connections in terms of clinical outcomes are scarce. Accordingly, the aim of this study was to compare radiographic marginal bone loss (RMBL) and associated implant complications between implants with internal hexagon (IH) connections and those with internal conical (IC) connections.

Advanced Biomaterials and Techniques for Oral Tissue Engineering and Regeneration-A Review.

The reconstruction or repair of oral and maxillofacial functionalities and aesthetics is a priority for patients affected by tooth loss, congenital defects, trauma deformities, or various dental diseases. Therefore, in dental medicine, tissue reconstruction represents a major interest in oral and maxillofacial surgery, periodontics, orthodontics, endodontics, and even daily clinical practice. The current clinical approaches involve a vast array of techniques ranging from the traditional use of tissue grafts to the most innovative regenerative procedures, such as tissue engineering.

Effects of a Short Drilling Implant Protocol on Osteotomy Site Temperature and Drill Torque.

Purpose: To establish a protocol for reducing the drilling sequence during implant site preparation based on temperature and insertion torque. The traditional conventional drilling sequence (used several drills with 0.6-mm increment each time) was compared with the proposed short drilling protocol (only used 2 drills: initial and final drill).

Utilization of Ceramic Inlays for Sealing Implant Prostheses Screw Access Holes: A Case-Control Study.

Purpose: The aim of this study was to evaluate, in a case control study, the esthetic and functional clinical performance of ceramic inlays used for covering the screw access hole in single monolithic lithium disilicate full-contour crowns bonded on computer-aided design/computer-aided manufacturing (CAD/CAM) prefabricated titanium abutments in order to eliminate the drawbacks of alternative restorative methods.

Materials And Methods: Twenty-eight patients with missing teeth in the lateral areas (premolars and molars) received screw-retained implant restorations. In half of the restorations (n = 14), composite fillings were used to seal the access hole (control group), while the other half was sealed with ceramic inlays (test group).

The assessment of lower face morphology changes in edentulous patients after prosthodontic rehabilitation, using two methods of measurement.

Using two measurement methods (a three-dimensional laser scanning system and a digital caliper), this study compares the lower face morphology of complete edentulous patients, before and after prosthodontic rehabilitation with bimaxillary complete dentures. Fourteen edentulous patients were randomly selected from the Department of Prosthodontics, at the Faculty of Dental Medicine, "Victor Babes" University of Medicine and Pharmacy, Timisoara, Romania. The changes that occurred in the lower third of the face after prosthodontic treatment were assessed quantitatively by measuring the vertical projection of the distances between two sets of anthropometric landmarks: Subnasale - cutaneous Pogonion (D1) and Labiale superius - Labiale inferius (D2).

Crestal bone remodeling around implants placed using a short drilling protocol.

Purpose: The aim of the study was to examine the influence of a short drilling protocol on peri-implant crestal bone levels.

Materials And Methods: Forty implants were placed in the posterior mandibles of 20 patients. The implants (diameter, 4.

Implant survival rate and marginal bone loss of 6-mm short implants: a 2-year clinical report.

Purpose: This study aimed to evaluate (1) the association between implant diameter and marginal bone loss (MBL) of short (6 mm) implants and (2) the survival rates of short implants.

Materials And Methods: Thirty-three 6-mm implants were placed in the mandibles of 16 qualified patients. The selected sites had > 5 mm ridge width and < 9 mm bone height.

Craniofacial morphology in patients with Angle Class II division 2 malocclusion.

Cephalometric analysis is frequently used in orthodontics for diagnostic purposes, in order to evaluate the positional relationship of the upper and lower jaw to the cranial base, as well as to objectively asses the way dental arches relate to one another and to the skeletal base. As with other dento-skeletal anomalies, the normal growth process can induce changes in these parameters. The purpose of this study is to evaluate the skeletal and dental changes that occur in growing patients with Angle Class II division 2 malocclusion.

Effects of a hydrogel patch on denture-related traumatic ulcers; an exploratory study.

Purpose: The aim of this exploratory study was to evaluate the effects of hydrogel patch wound dressing on healing time and pain level of denture-related lesions of the oral mucosa in edentulous individuals.

Materials And Methods: Twenty-three adults with newly fabricated complete sets of dentures who subsequently developed at least two ulcerative lesions related to their complete dentures were included in the study. For each participant, the smaller lesion (control lesion) was allocated to usual care, that is, adjustment of the denture's margins, whereas the larger lesion (test lesion) was assigned to receive usual care plus application of a hydrogel patch.

The influence of remaining alveolar bone upon lateral window sinus augmentation implant survival.

Unlabelled: BACKGROUND OF PROBLEMS:: Sinus augmentation is a predictable procedure to increase bone height in the posterior maxilla to facilitate ideal implant placement. However, the effect of residual alveolar bone height upon overall implant success remains unclear.

Aims: : Hence, the objective of this study was to review and evaluate the correlation between amount of remaining crest alveolar bone before sinus augmentation and implant survival rate in grafted areas.

A rough surface implant neck with microthreads reduces the amount of marginal bone loss: a prospective clinical study.

Objectives: An intra-individual controlled clinical trial was conducted to evaluate and compare the amount of marginal bone loss (MBL) found around implants of a comparable design, with or without retention grooves (microthreads) or polished necks, during the early stages of healing.

Materials And Methods: Forty-eight (48) patients with missing mandibular posterior teeth were treated with two commercially available implants of the same brand (MIS): one with microthreads (S-model) and the other with a polished neck (L-model). MBL around each implant was measured on follow-up radiograms taken 4 months after placement (exposure and crown cementation), and 6 and 12 months after loading.

Piezosurgery: basics and possibilities.

Useful in a variety of oral surgery procedures, piezosurgery has therapeutic features that include a micrometric cut (precise and secure action to limit tissue damage, especially to osteocytes), a selective cut (affecting mineralized tissues, but not surrounding soft tissues), and a clear surgical site (the result of the cavitation effect created by an irrigation/cooling solution and oscillating tip). Because the instrument's tip vibrates at different ultrasonic frequencies, since hard and soft tissues are cut at different frequencies, a "selective cut" enables the clinician to cut hard tissues while sparing fine anatomical structures (e.g.
