Since the distribution of the wire with respect to the bracket determines the moment-to-force ratio, and tooth movement is produced by the deactivation of the loop itself, friction is not an issue.5 There is a greater constancy of force in the Tear drop loop. Although TAD’s have been widely used for anchorage reinforcement, there are unpredictable factors such as anatomical limitations and the possibility of failure.6,7 However, precise control of tooth movement is possible in a predictable manner with the Tear drop loop. The Tear drop loop with a symmetric shape could be used to achieve a moment differential. Maintenance of the moment differential as the extraction spaces close, improves anchorage control and force system predictability.8, 9,10 CONCLUSION A patient with protrusion of maxillary and mandibular anterior teeth was treated successfully by maximum retraction using a Tear drop loop. The treatment results were
Farshchian and Kaiser in their article have reported the success of a molar bisection with subsequent bicuspidization . They stated that the success of bicuspidization depended on three factors which included 1. Stability and adequate bone support for the individual tooth sections 2. Absence of severe root fluting in the distal aspect of the mesial root or in the mesial aspect of the distal root 3. Adequate separation of the mesial and distal roots to create an acceptable embrasure for effective oral
_It does not harm other teeth as it is applied alone without getting a support from a tooth, hence it does not damage the other tooth. _Prevents bone loss: A tooth extraction or loss of tooth causes a physiological loss in the bone tissue around the extraction or loss. If a dental implant is applied to the recent extraction site, the bone loss does not occur. Hence, the implant treatment is the best choice to maintain the bone on the extraction site. It does not cause any deterioration in the mouth and tooth structure of the person because it looks like a natural tooth.
Overdentures allow an individual to bite and chew more naturally. They are comfortable because these dentures are anchored, which translates into less movement. The implants preserve the jaw bone that remains; whereas, traditional dentures do not. Fixed Dentures Whereas, overdentures can be removed, fixed dentures
Chapter 6 Dental Emergencies Dental problems demanding immediate intervention are termed as dental emergencies. Situations which can wait for normal dental appointments are not emergencies. Conditions demanding an emergency call are classified as: I. Oro – facial pain 1. Cuts or wounds to oral tissue 2. Prolonged tooth ache 3.
Hemisection refers to the sectioning of mandibular molar into two halves followed by removal or separation of diseased root with its accompanying crown portion.1 The procedure of hemisection represents a form of conservative management to retain maximum tooth structure as possible.2 Hemisection of either a maxillary or mandibular molar is often a means of retaining teeth needed for restorative abutments or occlusal support. This treatment can produce predictable results as long as proper case selection is followed by interdisciplinary approach with endodontic, surgical and prosthetic procedures.3. The results are durable, and success rates are high if certain basic considerations are taken into account. Periodontal, prosthodontic and endodontic assessment for appropriate selection of cases is important. In periodontics this procedure is indicated in class II furcation involvement and if there is considerable bone available to one
The same treatment options are available as the previous situation, however, pulp therapy must be performed. Follow up should be done to monitor the tooth. Root Fracture: this involves a fracture of the tooth across the root through the cementum, dentin and pulp. The fracture can be either in the cervical, middle, or apical third of the
Meanwhile, there are some things that you can do so as to assess the situation. In general, teething is largely associated with very mild symptoms. This is true for earaches that are associated with teething. The ear discomfort does not worsen when it is due to teething. If there is a lot of pain having extreme fussiness or if there is discharge that is coming from the ear, it is time to visit a doctor.
The frontal sinus is therefor able to communicate with, and drain its contents into the ostiomeatal complex because of the connection between its frontonasal duct (recess) and the ethmoidal infundibulum. The uncinate process, which forms the anterior and medial limitation of the hiatus semilunaris and the ethmoidal infundibulum (respectively), is a thin, crescent shaped, bony leaflet that emerges from the ethmoidal labrynth
The proposed core advantages of self-ligating system19 ● More certain full archwire engagement ● Low friction between the bracket and the archwire ● Greater arch expansion with less incisor proclination ● Faster archwire ligation and removal Particularly, claims that more stable transverse arch expansion with minimal incisor proclination can be achieved with self-ligating systems, offer a paradigm shift in treatment that entails fewer extractions and more arch expansion.17 However, it subsequently raised questions about the stability of results and the feasibility of long-term retention provided by this technique.16 Dwight Damon (1998)17 clarified the dubiety with his philosophy of ‘Bioadaptive response’ and ‘Biozone’.
