In-house Aligners: Why We Should Fabricate Aligners in Our Clinics?

As digital dentistry is evolving, contemporary orthodontics is embracing clear aligners as a tool more than ever before. On the other hand, aligners are being marketed to patients by aligner companies in every way that is possible. The demand of the end user and the pursuit of the orthodontist toward less chair time has made aligners popular in the last decade.

Evaluation of buccolingual molar inclinations among different vertical facial types.

Objective: The aim of this study was to compare the buccolingual inclination of maxillary and mandibular molars in adults with different vertical facial types.

Methods: Cone-beam computed tomography images of 135 adult patients (age, 20-45 years) with skeletal Class I maxillomandibular relationships were assigned to normodivergent (n = 46), hypodivergent (n = 49), and hyperdivergent groups (n = 40) according to linear and angular sella-nasion/gonion-menton measurements. The normodivergent group consisted of 24 females and 22 males, hypodivergent group of 26 females and 23 males, and hyperdivergent group of 24 females and 16 males.

Treatment of a Class II Case with Palatally Inserted Distalization Mechanics in an Epilepsy Patient.

This case report describes the protocol employed in the treatment of a patient with Class II malocclusion with mechanics including palatally positioned miniscrews.

Maxillary buccal cortical plate inclination at mini-screw insertion sites.

Objective: To evaluate whether buccal cortical bone inclination varies for the maxillary alveolar processes of adult patients with decreased, normal, and increased facial heights.

Materials And Methods: Cone-beam computed tomography images of 135 adult patients, including 49 hypodivergent subjects (26 women, 23 men), 40 hyperdivergent subjects (24 women, 16 men), and 46 normodivergent (25 women, 21 men) were analyzed. Cortical bone inclination measurements were made relative to the occlusal plane.

Pulpal thermal changes following Er-YAG laser debonding of ceramic brackets.

Lasers are effective in debonding ceramic brackets. Unfortunately, while reducing the adhesive bond strength, lasers are also reported to increase pulpal temperature. The aim of this study was to evaluate the shear bond strengths and temperature increase levels after debonding ceramic brackets using an Er-YAG laser with or without water-cooling.

Cortical bone thickness of the adult alveolar process--a retrospective CBCT study.

Objectives: To investigate and compare cortical bone thickness of the posterior alveolar process in adult patients presenting with skeletal Class I, II and III malocclusions.

Methods: Cone beam computed tomographic (CBCT) images of 196 adult subjects, aged 20-45, were evaluated. Cortical bone thickness was measured 4 mm from the alveolar crest, as the shortest bucco-lingual dimension of the cortical bone at interdental sites from the distal of the maxillary canine to the mesial of the maxillary second molar.

Effects of a newly designed apparatus on orthodontic skeletal anchorage.

Objective: An appliance was designed to increase the cortical bone surface contact area of miniscrew implants (MSIs). The purpose of this in vitro study was to evaluate the effects of this appliance on the anchorage force resistance and the stability of orthodontic MSIs.

Materials And Methods: A total of 48 MSIs were placed into bone specimens prepared from the ilium of bovines.

Quantitative evaluation of alveolar cortical bone density in adults with different vertical facial types using cone-beam computed tomography.

Objective: The purpose of this study was to quantitatively evaluate the cortical bone densities of the maxillary and mandibular alveolar processes in adults with different vertical facial types using cone-beam computed tomography (CBCT) images.

Methods: CBCT images (n = 142) of adult patients (20-45 years) were classified into hypodivergent, normodivergent, and hyperdivergent groups on the basis of linear and angular S-N/Go-Me measurements. The cortical bone densities (in Hounsfield units) at maxillary and mandibular interdental sites from the distal aspect of the canine to the mesial aspect of the second molar were measured on the images.

A report on the use of Er:YAG laser for pilot hole drilling prior to miniscrew insertion.

The aim of the present in vitro study was to investigate the required time period of the Er:YAG laser that is used for drilling through cortical bone when pilot hole drilling is needed before miniscrew insertion. Even though Er:YAG laser is used in various in vivo and in vitro studies, there is no accepted procedure of laser for depth control during drilling through cortical bone. The study sample consisted of 120 cortical bone segments having 1.

Cortical bone thickness of the alveolar process measured with cone-beam computed tomography in patients with different facial types.

Introduction: The purpose of this study was to determine the cortical bone thickness of the alveolar process in the maxilla and the mandible on cone-beam computed tomographs of adults with low, normal, and increased facial heights.

Methods: This study was conducted on 155 images of adult patients (20-45 years old) who were assigned to the low-angle, normal, and high-angle groups. The thickness of the buccal cortical plates of the maxilla and the mandible, and the palatal cortical plates of the maxilla, were measured.

FEM analysis of a new miniplate: stress distribution on the plate, screws and the bone.

Objectives: Non-homogeneous force distribution along the miniplates and the screws is an unsolved question for skeletal anchorage in orthodontics. To overcome this issue, a miniplate structure was designed featuring spikes placed on the surface facing the cortical bone. The aim of this study was to examine and compare the force distribution of the newly designed plate-screw systems with the conventional one.

Comparison of shear bond strengths of ceramic brackets after different time lags between lasing and debonding.

Laser use is effective in the debonding of ceramic brackets. However, a standardization of the laser debonding techniques used has not yet been implemented. The purpose of this study was to evaluate the effect of the time lag elapsed between lasing and shearing on debonding of ceramic brackets.

Effects of different application durations of scanning laser method on debonding strength of laminate veneers.

Porcelain laminate veneers as esthetic and minimally invasive restorations are being used as an alternative to full veneer crowns. However, the removal of porcelain veneers that have failed may be an uncomfortable and time-consuming procedure because of the high bond strength between the porcelain laminate veneers and the tooth surface. The purpose of this study was to prepare a simple and reliable method for porcelain laminate veneer debonding by using an Er:YAG laser with the scanning method and to determine the amount of lasing time required.

Debonding of ceramic brackets by a new scanning laser method.

Introduction: The purpose of this in-vitro study was to develop a new method to debond ceramic brackets by scanning with an Er:YAG laser.

Methods: Sixty bovine mandibular incisors were randomly divided into 2 groups of 30. Polycrystalline ceramic brackets were placed on their labial surfaces by using the orthodontic composite adhesive Transbond XT (3M Unitek, Monrovia, Calif) and light cured for a total of 40 seconds.

Effects of different application durations of ER:YAG laser on intrapulpal temperature change during debonding.

This study was done to determine the amount of lasing time required to remove ceramic brackets safely without causing intrapulpal damage by using Er:YAG laser with the scanning method. Part 1: 80 bovine mandibular incisors with ceramic brackets were randomly assigned into four groups of 20 as one control and three study groups. In the study groups, brackets were debonded after lasing for 3, 6, and 9 s, whereas debonding was performed without lasing in the control group.
