1/77. Is lower incisor extraction treatment a compromise?In this paper orthodontic treatment involving extraction of a lower incisor is described. This has traditionally been regarded as a compromise as loss of a lower incisor renders it impossible to achieve true ideal occlusion. However, with careful case selection, treatment planning and visualization of the post-treatment occlusion, excellent functional and aesthetic results can be achieved. The various factors that govern the decision to treat certain malocclusions in this way are discussed and a clinical case is presented to demonstrate this type of treatment.- - - - - - - - - - ranking = 1keywords = extraction (Clic here for more details about this article) |
2/77. The role of orthognathic surgery in the treatment of severe dentoalveolar extrusion.BACKGROUND: When mandibular molars are not replaced after extraction, the long-term problem of inadequate interarch space for either a fixed or removable prosthesis can occur. In the past, practitioners needed to decide whether to shorten the teeth, extract the supererupted maxillary molars to recapture space or leave the area unrestored. The authors present another option. CASE DESCRIPTION: A 61-year-old man was referred to a periodontist by his general dentist for placement of mandibular implants in the posterior sextant. Extreme supereruption of the maxillary dentoalveolar segment prevented restoration of the opposing edentulous area. An oral and maxillofacial surgeon performed a segmental osteotomy of the posterior right maxilla to gain needed interarch space. After the osteotomy was stabilized, the periodontist placed implants that were subsequently restored with a fixed prosthesis. CLINICAL IMPLICATIONS: The role of orthognathic surgery in treatment planning should not be overlooked in the comprehensive management of severe extrusion. It offers patients the opportunity to gain both function and esthetics that might otherwise be impossible.- - - - - - - - - - ranking = 0.2keywords = extraction (Clic here for more details about this article) |
3/77. Multiple extraction patterns in severe discrepancy cases.Thirty-five cases have been collected from colleagues which illustrate that removal of additional maxillary teeth, following first bicuspid extractions, can allow the successful resolution of difficult discrepancy and anchorage cases. charts 1 and 2 describe the amounts of space that might be expected by removal of additional upper bicuspids, upper first molars, and upper second molars. The findings on upper second molars are admittedly limited. Anchorage values as expressed by an efficiency percentage were approximately what would be expected from a study of anchorage values of the roots of teeth. The removal of upper second bicuspids has a better anchorage efficiency potential than the upper first molar, but this may be overcome somewhat by the greater size of the molar. Clear guidance cannot be given as to which teeth to remove in a specific case, but it is the observation of the author that for cases that are still in full Class II following four bicuspid space closure, upper second bicuspid removal would be more helpful from an anchorage perspective, whereas for cases that are in end-to-end molar relationship or require only a few millimeters to move into Class I, the upper first molar might be the tooth of choice. Also, the supper first molar removal allows for a more "normal" appearing arch assuming normal alignment and size of the upper second and third molars. The comparison with the nonextraction control group showed an enormous difference in the amount of incisor retraction that extractions provide when related to the maxilla. The nonextraction control group, though experiencing dramatic correction of Class II relationships, showed no incisor movement within the maxilla. Some problems which appeared in the sample were described. Removal of upper teeth in addition to the four first bicuspids can be a solution to an occasional anchorage, skeletal, growth or cooperation problem.- - - - - - - - - - ranking = 1.6keywords = extraction (Clic here for more details about this article) |
4/77. Second premolar serial extraction.serial extraction of mandibular second premolars should be considered if they are impacted or in cases with moderate arch length deficiency combined with an absence of dentofacial protrusion. The favorable dental changes associated with this approach greatly minimize future orthodontic treatment complexity and time.- - - - - - - - - - ranking = 1keywords = extraction (Clic here for more details about this article) |
5/77. Second molar replacement applied to dentofacial orthopedics and orthodontics much more than a technique.There is seldom a consensus on any dental subject. The literature contains conflicting points of view and results of studies vary considerably. I have endeavored to present my paradigm of second molar replacement in dentofacial orthopedics and orthodontics. I have presented a summation of information known to date regarding this subject. I based this article on my extensive clinical experience and observations over many years. I participate in continuing education, and know many of the traditional and functional post-doctoral educators. I read the literature. For your benefit, I have presented this information and shared a paradigm that has positively changed my life, and perhaps will change the way you practice. Second molar replacement technique has revolutionized orthodontic treatment. The technique offers distinct benefits considering the patient's face, the jaw joints, and the teeth. The reader is strongly encouraged to read bibliography references for a mature understanding of second molar replacement in modern orthodontics and TMD therapy. When extraction of teeth is needed for orthodontic purposes Broadbent considers second molar replacement, second bicuspid removal, first bicuspid removal, lower incisor removal, and then other extraction possibilities to resolve the malocclusion. When extraction guidelines are followed and treatment mechanics are properly designed the extraction of second molars have predicable good results in a high percentage of cases. However, second molar removal may be contraindicated for numerous reasons. diagnosis and case selection is paramount! The doctor must diagnosis and determine if and when second molar replacement would be in each patient's best interest. The bottom line for each individual patient is the best possible facial esthetics, functional occlusion, and health of jaw joints.- - - - - - - - - - ranking = 0.8keywords = extraction (Clic here for more details about this article) |
6/77. The Royal london Space Planning: an integration of space analysis and treatment planning: Part II: The effect of other treatment procedures on space.The Royal london Space Planning process is carried out in 2 stages. The first stage, assessing the space required to attain the treatment objectives, was described in Part I of this report, published earlier. In Part II, the process of integrating space analysis with treatment planning continues with consideration of the effects other treatment procedures have on space. These procedures include tooth enlargement or reduction, tooth extraction, the creation of space for prosthetic replacement, and mesial and distal molar movement. The effects of favorable and unfavorable growth are also considered. A brief case report is presented to demonstrate use of the Royal london Space Planning.- - - - - - - - - - ranking = 0.2keywords = extraction (Clic here for more details about this article) |

8/77. Non-extraction treatment of a thirteen-year-old boy with a Class III skeletal discrepancy and severe crowding in both the upper and lower dentitions.A thirteen-year-old boy presented with a Class III skeletal tendency in association with severe crowding in both the upper and lower arches. Whilst there was not a frank posterior crossbite, it was felt that the upper arch was narrow and that the lower arch was similarly constricted. Taking this into account along with the fact that his upper lip was flat and the nasolabial angle obtuse, it was decided to pursue a non-extraction treatment, with the aim of providing by expansion an extra 16 mm of space in the upper arch and 8 mm in the lower arch to accommodate the full dentition, and with a view to extracting third molar teeth later. This proved to be successful, albeit over an extended period of time, with active treatment taking nearly three and a half years. A realistic alternative would have been to remove four bicuspid teeth and pursue an orthodontic/surgical approach to treatment. In retrospect, and with the benefit of reviewing his records without surgical intervention, the treatment plan decided upon has been well justified.- - - - - - - - - - ranking = 1keywords = extraction (Clic here for more details about this article) |
9/77. Conservative management of malocclusion in mixed dentition.The treatment planning in mixed dentition period has changed from extraction to non extraction. Any orthodontic treatment must take into consideration the growth trends and the pubertal growth spurt. The two cases presented here were treated during mixed dentition period in different ways: one with fixed appliances and the other with removable myofunctional appliance therapy, with satisfactory results. Hence for a conservative treatment approach, the non-extraction treatment is recommended in mixed dentition period.- - - - - - - - - - ranking = 0.6keywords = extraction (Clic here for more details about this article) |
10/77. Effect of facial pressure garments for burn injury in adult patients after orthodontic treatment.pressure garments are commonly used to prevent and control hypertrophic scar tissue. Complications are unusual, though in children with facial burns, pressure garments may lead to skeletal and dental deformities. Studies in adolescents and adults are sparse. We describe a 24-year-old woman who sustained facial burns. Prior to injury, the patient had undergone premolar extraction in preparation for orthodontic treatment. Her post-burn care consisted of application of a Jobst pressure garment. After 2 months treatment, severe deformation of the dental-alveolar structure was observed. This reports suggests that adults after dental extraction are at a high risk of dental-alveolar deformities from pressure garments and might benefit from the use of occlusal wafers.- - - - - - - - - - ranking = 0.4keywords = extraction (Clic here for more details about this article) |
