Copy-paste concept: Full digital approach in the management of gingival emergence profiles
Obtaining a perfect integration of a prosthetic rehabilitation on natural teeth and implants in the esthetic zone requires a deep knowledge of the biological processes and a clear understanding of the characteristics of the restorative materials. Once the soft tissue profile has been created with the placement of a temporary prosthesis, the ability to accurately transfer information about the tissue profile and the contour of the restoration for the fabrication of the definitive crowns can be challenging.

The Socket Shield Technique with Promixal Extensions for Single-Rooted Teeth
The conventional socket shield (SS) design extends from the mesiolabial to the distolabial line angle. C-shaped SS, L-shaped SS, and proximal SS designs have proximal extensions that help to maintain the hard and soft tissue in the interproximal areas. This is beneficial for implant sites adjacent to an existing implant or an edentulous space. The most common complication of the socket sheild technique (SST) is internal shield exposure. Due to anatomical features such as a scalloped ridge shape and an oval socket shape of some teeth, the risk of complications such as internal shield exposure, inadvertent SS displacement, and fracture of the SS during implant insertion is greater in proximal shield areas. The present article describes guidelines for case selection for proximal shield extensions, along with SS preparation and the selection of implant and prosthetic components.

Root Submergence Technique, A Case Series with Follow-Up up to Seven Years
In the era of aesthetic dentistry, the goal is not only to provide a function to our patients but also to preserve the hard and soft tissue anatomy, to have a pleasing prosthesis. Obtaining natural aesthetics is simpler in single implant cases, however, in multiple implant prosthesis achieving natural dentition becomes a challenge. The root submergence technique (RST) is one such procedure that provides maximum preservation of the surrounding alveolar bone and soft tissue. This case series discusses the effect of a root submergence technique on preserving the periodontal tissue at the pontic site of fixed dental prostheses in the maxillary arch. The results of this clinical case series indicate that a root submergence technique can be successfully applied in the pontic site development with fixed dental prostheses, especially in the maxillary anterior aesthetic zone.

Three-Dimensional (3D) Facially Driven Workflow for Anterior Ridge Defect Evaluation: A Treatment Concept
The esthetic rehabilitation of anterior ridge defects and achieving patient satisfaction have become major clinical challenges for dentists and technicians. Poor diagnosis and treatment planning are frequently associated with multiple surgical procedures that fail to meet patient expectations. The loss of hard and soft tissues in anterior ridges results in an esthetically compromised zone that affects the rehabilitation prognosis. The presence of interdental papilla and papillary configuration play a decisive role in patient satisfaction.

Treating Two Adjacent Missing Teeth in the Esthetic Zone - Part 1: The Pink Hybrid Restoration & the Unilateral Versus Bilateral Defect Concept
This article, the first of a planned three-part series, outlines a new surgical & prosthetic approach for treating cases involving two missing adjacent teeth in the esthetic zone. These type of cases, particularly when combined with a three-dimensional ridge deficiency, represent one of esthetic dentistry's most challenging dilemmas. A Clear understanding of the unilateral and bilateral defect concept is necessary to properly evaluate each particular case, understand surgical limitations, perform a better risk assessment, establish an esthetic prognosis, develop the best clinical-laboratory strategy, and adjust patients' expectations. While not recommended for every case, represents a useful, economical, and predictable alternative that decreases the umber and complexity of interventions.

Antimicrobial Effect of a Single Dose of Amoxicillin on the Oral Microbiota
Amoxicillin is commonly used in oral surgery for antimicrobial prophylaxis against surgical-site infection and
bacteremia because of its effect on oral streptococci. The aim of this study was to determine whether amoxicillin reaches
the break-point concentrations in saliva and has any effect on the salivary microbiota, colonizing bacteria on mucosal
membranes and on the gingival crevice after a single dose of amoxicillin. A single dose given as prophylaxis to prevent a surgical-site infection results in a significant reducing effect on
the oral streptococcal microflora in the gingival crevice and may have an impact on bacteria spreading into tissues and the
bacteria of streptococci.

Effectiveness of a Super-Pulsed CO2 Laser For Removal of Biofilm From Three Different Types of Implant Surfaces: An In Vitro Study
As dental implants become
a routine part of dental practice, so too will the
prevalence of peri-implant diseases. Inherent
to the treatment of peri-implant disease is the
removal of microbial biofilms from the implant
surface. Currently, there is no standardized
protocol for application of any treatment
modality directed at implant surface decontamination.
In this in vitro study, we report
on the effectiveness of a super-pulsed CO2
laser, delivering an
average fluence of 6.3 to 113 J/cm2, to
remove biofilm from three different types of
implant surface topographies.
Biofilms ranged in thickness from
5 to 15 μm. An average fluence of 19 J/cm2
was sufficient to achieve 100% ablation of the
biofilm on hydrophilic sandblasted and acidetched
surface specimens (SA). However, to
achieve 100% ablation of biofilm on HA and
highly crystalline, phosphate enriched titanium
oxide (PTO) surfaced implants required an
average fluence of 38 J/cm2.

Oral Soft Tissue Laser Ablative and Coagulative Efficiencies Spectra
The key to the success of soft tissue
lasers is their ability to cut and coagulate the
soft tissue at the same time. Present work is
aimed to derive the wavelength-dependent
differences in photo-thermal ablation and
coagulation efficiencies for oral soft tissue
pulsed dental Near-IR Diode, Mid-IR Erbium
and IR CO2 lasers. Even though the soft tissue photothermal
ablation has been extensively
studied, there remains a discrepancy
between (a) the widely proliferated notion
about efficient Near-IR 800-1,100 nm laser
ablation of the oral soft tissue, and (b)
studies reporting the inefficient soft tissue
Near-IR absorption/ablation. Indeed, the notions about “the key to
the usefulness of the Nd:YAG is that this
wavelength is highly absorbed in oral soft
tissue”, and “all currently available dental
laser instruments and their emission wavelengths
have indications for use for incising,
excising... oral soft tissue surgery”,
contradict an observation illustrated here...

Decision Making for Soft and Hard Tissue Augmentation in Surgically Facilitated Orthodontics
The purpose of this article is to present a decision-making algorithm for soft and hard tissue augmentation in surgically facilitated orthodontics (SFOT). In cases where there is adequate hard and soft tissue envelope, selective corticotomies may be adequate.
In cases, where the existing hard and soft tissue anatomy is inadequate, hard and soft tissue augmentation is recommended. Also, hard and soft tissue augmentation is recommended to avoid teeth extractions during orthodontics.

Manejo Integral de Maloclusion Clase III en Adulto, con Requerimientos Periodontales y Protesicos; Reporte de un caso clinico
En nuestra clinica observamos un aumento de pacientes adultos con problemas esqueletales, compromiso periodontal y necesidades protesicas. Debemos recurrir a la interconsulta con el periodoncista, protesista y cirujano maxilofacial, para la correccion del caso, prestando especial atencion al componente dentario, esqueletal y los tejidos blandos faciales del paciente. La cirugia ortognatica, que generalmente la realizamos luego de una preparacion ortodoncica, permite corregir discrepancias en el adulto y restaurar la funcion y estetica en los tres planos del espacio. Realizada la correccion oclusal, procedemos a sustituir dientes ausentes, mediante implantes y protesis fijas. El Periodoncista, mantiene un control constante de la salud de los tejidos de soporte, durante todas las fases de la terapia multidisciplinaria.

Sequencing of Periodontal Procedures and Orthodontic Treatment
Severe cases of periodontal disease often require periodontal surgery and realignment of teeth. Surgical techniques have been developed that attempt to minimize post-surgical gingival recession and compromise the interdental papillae. A case report is presented in which reversal and correction of a deteriorating maxillary frontal dentition were effectively achieved through combined use of periodontal and orthodontic principles. The treatment plan included the control of periodontal inflammation, restoration of lost attachment apparatus, realignment of anterior dentition, stabilization of occlusion, and minor periodontal plastic surgery. The anticipated loss of a maxillary lateral incisor was avoided. Restoration of a pleasant smile with nicely aligned teeth and esthetic gingival contours was achieved. The correct sequencing of the procedures involved was considered a key factor for the long-term esthetic outcome.
