Part I of this paper describes the background, general concepts, available techniques and clinical applications recording external craniofacial morphology in three dimensions. II explores different 3D imaging dental arches, their possible uses orthodontic diagnosis treatment.

No randomized controlled trial has tried to compare treatment outcomes between the sliding en-masse retraction of upper anterior teeth supported by mini-implants and two-step technique employing conventional anchorage devices.To evaluate skeletal, dental, soft tissue changes following retraction.Parallel-groups on patients with class II division 1 malocclusion treated at University Al-Baath Dental School in Hamah, Syria July 2011 May 2013.One hundred thirty-three an dentoalveolar protrusion...

To evaluate the effectiveness of two minimally invasive surgical procedures in acceleration canine retraction: piezocision and laser-assisted flapless corticotomy (LAFC). Trial design: A single-centre randomized controlled trial with a compound design (two-arm parallel-group split-mouth for each arm). Participants: 36 Class II division I patients (12 males, 24 females; age range: 15 to 27 years) requiring first upper premolars extraction followed by retraction. Interventions: group (PG; n =...

No randomized controlled trial (RCT) has compared flapless piezocision-assisted corticotomy in the extraction-based orthodontic decrowding of lower anterior teeth with conventional treatment.To evaluate effectiveness corticotomies accelerating alignment.A parallel-group RCT was conducted.Thirty-six patients (mean age 20.32 ± 1.96 years) need treatment a fixed appliance were enrolled and randomly allocated to either experimental or control group. Following first premolar extraction, five...

Objective This study investigated periodontal health changes in adult patients with mild crowding, undergoing treatment a modified Inman appliance. Materials and methods prospective cohort involved 16 malocclusion (4 males 12 females; mean age 21.94 ± 2.26 years) crowding. Participants were treated using Plaque Index (PI), Gingival (GI), Papillary Bleeding (PBI) measured at four assessment times: before (T0), two weeks (T1), one month (T2), months (T3) after appliance placement. Results All...

Objective To compare the level of oral health-related quality life (OHRQoL) between patients receiving clear aligners or fixed appliances within one year follow-up using Oral Health Impact Profile 14 (OHIP-14), a validated self-administered questionnaire. Materials and methods A single-centered, two-arm parallel-group randomized controlled clinical trial was conducted on 36 adult (19 females, 17 males; age range: 18 to 25 years) who had severe crowding require orthodontic treatment with...

Background and objectives Recently, both surgical non-surgical interventions have gained popularity in accelerating orthodontic tooth movement, but there is no randomized controlled trial (RCT) comparing modalities terms of patient-reported outcome measures (PROMs) during maxillary canine retraction. Therefore, this aimed to assess the PROMs associated with either low-level laser therapy (LLLT) or piezocision-assisted acceleration context Materials methods This was a single-blinded,...

ABSTRACT Objectives: To compare (1) speech performance based on an auditive analysis and sonagraphy (2) levels of oral impairment between fixed lingual labial orthodontic appliances. Materials Methods: Thirty-four patients with Class I division 1 malocclusion moderate crowding upper teeth were distributed randomly into two groups. Seventeen in group A (mean age: 20.6 years; standard deviation [SD]: 2.9 years) treated appliances (Stealth®, AO, Sheboygan, Wisc), whereas 17 B 21.8 SD: 3.3...

Hawley retainers (HRs) and vacuum formed (VFRs) are the most commonly used removable in orthodontic practice. Patients' cooperation wearing these appliances is affected by levels of discomfort oral impairment. The evidence regarding their acceptably among patients limited. To compare acceptability HRs VFRs over a 6-month period group fixed patients. Two-arm parallel-group randomized controlled trial. Patients being treated at Orthodontic Department Saudi Swiss Consultant Dental Centre,...

Increased awareness on the role of oral functions in aetiology Class II deformities has led to wide spread myofunctional training appliances as easy and possibly effective treatment for children with malocclusion but their efficacy is yet be proven.To evaluate soft- hard-tissue changes following 12 months division 1 growing patients a conventional functional appliance (a modified Activator) versus Trainer system (T4K®).Department Orthodontics, Dental School.Sixty (8-12 years old) were...

Objective: To compare the effectiveness and efficiency of in-house clear aligners with traditional fixed appliances in treating premolar-extraction-based complex cases. Materials methods: A single-centered, 2-arm parallel-group randomized controlled clinical trial was conducted on thirty-six (12 males, 24 females; mean age: 21.24 ± 2.33) patients severe crowding who required orthodontic treatment four first premolars extraction. The were equally randomly divided into two groups: (CA) group...

Background and Objectives: To compare the oral-health-related quality of life (OHRQoL) outcomes between patients treated with modified Ni-Ti spring-based alignment appliances or conventional fixed using Oral Health Impact Profile 14 (OHIP-14), as well levels satisfaction appliance appearance, treatment progress, outcomes. Materials Methods: Thirty-six (11 males, 25 females) were randomly divided into two groups: either aligner springs group (MAA) traditional (FA). The allocation ratio was...

Background.Comprehensive orthodontic treatment may last for 20-24 months.Reducing the time has become a common demand from both patients and orthodontists.Minimally invasive piezocision is one of suggested approaches to accelerate tooth movement.Objectives.The aim this randomized controlled clinical trial was assess effectiveness flapless procedure in accelerating retraction upper incisors. Material methods.A single-blinded, parallel-group conducted at Department Orthodontics University...
