Short CV

Dr. Vicente Sada received his dental training at the UOD (1991). He was certified in Orthodontics at the Universidad Intercontinental, Mexico D.F., Mexico (1994), and received a Master of Science in Orthodontics (1995).

He has a practice limited to orthodontics with special interest in adult patients in Pamplona (Navarra, Spain). He has completed many courses in the field of periodontics and lingual orthodontics. He holds certificates of achievement in Lingual Orthodontics Courses by Dr. Echarri in Barcelona (2000) and the One-year program in lingual orthodontics by Dr. Didier Fillion in Paris, France (2002) and Dr. Dirk Whiechmann in Bad Essen, Germany (2002 and 2010).

He is an active member of the European Society of Lingual Orthodontics and the World Society of Lingual Orthodontics. Dr. Sada has published papers on the interdisciplinary approach in the adult patient with emphasis on the relationship between Orthodontics and Periodontics and Lingual Orthodontics.

He is also key opinion leader for Incognito Unitek 3M.

 

 


 

ABSTRACT

 

Title: MAXILLARY TUBEROSITY MINISCREWS IN LINGUAL ORTHODONTICS: 

DESCRIPTION OF THE TECHNIQUE, BIOMECHANICS AND CLINICAL CASES.


Miniscrews for orthodontic treatment are usually placed in many locations (inter radicular, palatal, mandibular shelf, mandibular retromolar etc...), according to the patient’s anatomic possibilities and the biomechanical needs of the treatment. The maxillary tuberosity has been very rarely studied on literature and seldom clinically used, although it offers ideal conditions for many orthodontic movements, specially distalization and intrusion of the upper arch.

This location and technique has many advantages over other options: placement of screws is carried out easily in attached gingiva, there is no risk of root damage, procedure is fast, cheap, cost-effective and non-dependent on laboratory, and the location is the best strategic location to distalize and/or intrude the upper arch.

This technique, described by Vicente Sada -article ahead of publication- has been used since many years ago in many patients with excellent results, as we aim to show in different clinical cases treated with success. The preliminary results of a prospective, still ongoing study, that is being carried out by the authors regarding success rate, surgical technique and bio-mechanical analysis are also discussed.

PURPOSE: The purpose of the present study and presentation is to show the clinical possibilities of the maxillary tuberosity miniscrews for orthodontic upper arch movements: anatomic special considerations, surgical technique details and biomechanic analysis are explained based upon the experience of many clinical cases.

Success rate, surgical technique, bio-mechanical analysis are also described based on the preliminar results of a prospective, still ongoing study that is being carried out by the authors. 

MATERIAL AND METHODS: A prospective study is carried out on 17 patients treated with maxillary tuberosity miniscrews (n=37) for orthodontic treatment are followed during 160 days: torque of insertion of miniscrews, distance from second molar, millimeters of attached gingival, millimeters of insertion in bone, rate of success, biological consequences and other clinical parameters are measured and the results statistically analyzed.

RESULTS, DISCUSSION and CONCLUSIONS: Miniscrew success rate was high, with 94,6%, with only 2 miniscrews lost after 160 days, which is similar or slightly above other usual locations for TADs. Not significant differences were found in the technical or biological parameters analyzed regarding its implication in success/failure.

Maxillary tuberosity area presents a high success rate, and it is an ideal location for distalization and intrusion of upper arcade in combination with lingual orthodontics.
