NCT ID: NCT03354442 Recruiting - Clinical trials for Malocclusion, Angle Class III

Treatment of Class III Malocclusion Using Modified Fixed Mandibular Retractor Appliance

Start date: May 15, 2017
Phase: N/A
Study type: Interventional

This experimental study aims to evaluate the efficiency of the Modified Fixed Mandibular Retractor Appliance in the treatment of skeletal class III malocclusion. The study sample will consist of 44 patients with skeletal class III malocclusion. The sample will be allocated randomly into two groups: experimental group and untreated control group. The soft and hard tissue changes will be assessed using lateral cephalometric radiographs before the treatment and after obtaining 3mm positive overjet.

NCT ID: NCT03310086 Recruiting - Crowding, Tooth Clinical Trials

Acceleration of Lower Anterior Teeth Leveling and Alignment Using Corticision

Start date: January 2017
Phase: N/A
Study type: Interventional

This experimental study will evaluate the effect of corticision on accelerating the leveling and alignment of lower crowded incisors compared with the control untreated group using cone beam computed tomography. The study sample will consist of 26 patients with less than 6 mm crowding. The sample will be allocated randomly into two experimental groups. The brackets and passive SS wire will be applied with radiographic metal guides between each tooth to allow for accurate corticision site 2 mm below the gingival papilla and to prevent tooth roots injury. The dentoalveolar changes occurring after leveling and alignment of lower anterior teeth will be evaluated using CBCT radiographs, Frequency, degree of root resorption, and the incidence of bone dehiscence will be assessed in relation to initial situation.

NCT ID: NCT03305679 Recruiting - Clinical trials for Implant Site Reaction

Clinical Efficacy of the Immediate Implant Loading

Start date: January 19, 2017
Phase: N/A
Study type: Interventional

Aim: The aim of this study to Assess the healing process of the immediate implant loading with two different provisional techniques (direct and indirect). Materials and methods: 20 implant in the aesthetic zone either in the incisor or in the canine area and excluding the lateral location and then immediate loading is achieved for the 20 implants (10 for direct and 10 for indirect method) Clinical Aspect :color change , healing and bone resorption Esthetic assessment and patient acceptance will be assessed using specific tools. Lab aspect: surface roughness and Marginal fit will be measured to have clue vision.

NCT ID: NCT03279042 Active, not recruiting - Protrusion, Incisor Clinical Trials

Effectiveness of Two Corticotomy Techniques in Retracting the Upper Anterior Teeth by Using Miniscrews

Start date: September 12, 2016
Phase: N/A
Study type: Interventional

This study aims to evaluate and compare the skeletal, dental and soft tissue changes, the levels of pain and discomfort and the effect on periodontal health and teeth vitality associated to traditional corticotomy and flapless corticotomy in the retraction of upper anterior teeth. 40 patients requiring extraction of maxillary first premolars and maximum anchorage to retract the upper anterior teeth will participate in the study. They will be divided randomly into two groups : flapless corticotomy (20 patients) and traditional corticotomy (20 patients). Pre-retraction, corticotomy will be performed in the maxillary anterior segment. The skeletal, dental and soft tissue changes will be performed using lateral cephalometric radiographs which will be obtained pretreatment, pre and post en-masse retraction of the anterior teeth and we will also use the dental casts to evaluate the dental changes.

NCT ID: NCT03251807 Recruiting - Clinical trials for Malocclusion, Angle Class II

Effect of Low-Intensity Pulsed Ultrasound on Functional Treatment of Class II Malocclusion

Start date: August 1, 2017
Phase: N/A
Study type: Interventional

This experimental study will evaluate the effect of combined treatment with low-intensity pulsed ultrasound (LIPUS) and functional appliances (twin-block) on the correction of class II malocclusion, compared with the control group treated with functional appliances (twin-block) only. The study sample will consist of 40 patients with class II malocclusion. The sample will be allocated randomly into two groups: control group and experimental group. The functional appliance (twin-block) will be applied for all patients, while the low-intensity pulsed ultrasound (LIPUS) will be applied for the experimental group only. The skeleto-dental changes occurring after functional treatment will be assessed using cephalometric radiographs; pre and post- treatment changes for each group will be evaluated individually, and the two groups will be compared.

NCT ID: NCT03239912 Recruiting - Clinical trials for Malocclusion, Angle Class II

Treatment of Class II Malocclusion Combined With Low-level Laser

Start date: July 16, 2017
Phase: N/A
Study type: Interventional

This experimental study will evaluate the effect of combined treatment with low-level laser and functional appliances (twin-block) on the correction of Class II malocclusion, compared with the control group treated with functional appliances (twin-block) only. The study sample will consist of 40 patients with Class II malocclusion. The sample will be allocated randomly into two groups: a control group and an experimental group. Functional appliance (twin-block) will be applied for all patients. Low-level laser will be applied for the experimental group only. The skeleto-dental changes occurring after functional treatment will be assessed using cephalometric radiographs; pre- and post- treatment changes for each group will be evaluated individually.

NCT ID: NCT03226951 Recruiting - Clinical trials for Non Central Diabetic Macular Edema

SDM Laser for Non Central Diabetic CSME

Start date: July 1, 2017
Phase: N/A
Study type: Interventional

Is to determine if SDM laser can reduce macular thickness in non central CSME and stop the progression of non central CSME to central CSME in compare to glycemic control

NCT ID: NCT03172442 Recruiting - Clinical trials for Class III Malocclusion

Treatment of Skeletal Class III Malocclusion Using Orthodontic Removable Traction Appliance

Start date: May 1, 2017
Phase: N/A
Study type: Interventional

This experimental study aims to evaluate the efficiency of the orthodontic removable traction appliance in the treatment of skeletal class III malocclusion. The study sample will consist of 44 patients with skeletal class III malocclusion. The sample will be allocated randomly into two groups: experimental group and control group. The dentoskeletal changes will be assessed by using lateral cephalometric radiographs before treatment and after obtaining 3mm positive overjet.

NCT ID: NCT03163680 Active, not recruiting - Clinical trials for Peptic Ulcer Hemorrhage

Efficacy of Low Dose of Proton Pump Inhibitor in Treatment Bleeding Ulcers

Start date: January 2012
Phase: N/A
Study type: Observational

Determining the efficacy of low dose of PPI in management acute peptic ulcer bleeding

NCT ID: NCT03149016 Recruiting - Clinical trials for Class II Division 1 Malocclusion

The Use of Corticotomy for Upper Incisors Retraction

Start date: August 20, 2016
Phase: N/A
Study type: Interventional

We aim to assess the treatment outcomes following upper incisors retraction accelerated by corticotomy procedure. So, we intend to randomize orthodontic patients with class II division I malocclusion into two groups: experimental group and control group. Both groups will start orthodontic treatment. Once a 0.019*0.025-inch stainless steel wire is fully engaged to the brackets, 1st premolars will be extracted. Canines will be retracted in the conventional manner. Then, the actual evaluation period starts when the upper incisors are retracted using two different methods.
