TREATMENT of class III malocclusions (Karen Mcdonagh)

Although traditional orthodontic treatment, to develop class malocclusion, concentrated on the lower jaw as the primary cause of inconsistency, a recent study showed that 63% of skeletal class III malocclusions display the maxillary retrusion. Most patients tend to exhibit the maxillary hypoplasia with normal or mildly prognathic mandible.

Unfortunately I see too many young patients for a second opinion, which said that there is nothing to do but orthodontist can wait for their personal growth and then work for orthognathic surgery. Nevertheless, most surgical procedures to correct the bite class are the maxillary achievements! This shows that the problem has never been the excessive growth of the mandible, but rather a lack of development of the upper jaw. Such problems can caused by nasal blockages when the child was younger.

Orthodontic treatment for malocclusion class can be defined as follows:

1. Growth modification involving the maxillary expansion and protraction therapy facial mask

2. Growth modification with Chin Cup for controlling the growth of the mandible, or

3. Wait until the growth stopped, therefore, commitment to patient dental camouflage or orthognathic surgery.

In my orthodontic practice early signs of class III malocclusion in children, receive priority for treatment. My current approach of treatment involves inhaling and the development of the upper jaw, but I do not use Chin cups, as I feel that they have a negative impact on the patient, TMJ joint.

Currently exist regarding the optimal time to begin orthodontic treatment of class. Takada maxillary protraction therapy were studied and reported that the timing of the immature and the middle of pubertal better, due to the natural growth of the upper jaw (stage C2-C3).

THE GOAL OF TREATMENT FOR THE PATIENT:

If we treat the patient as early in the growth cycle as possible, i.e. as soon as can be diagnosed the problem of class III can be achieved following treatment goals:

1. the decline in the growth of the lower jaw.

2. increase the size of the upper jaw to the maximum genetic potential, and

3. move the jaw forward maximum genetic potential.

Cephalometric analysis is important to confirm the diagnosis of class III malocclusion and formulate a plan of surgical or non-surgical treatment.

I personally use the cephalometric analysis of Jefferson, as it's perfect for a proper diagnosis of the patient class III. In the analysis of the mandible size and Jefferson position the mandible can be easy with the length and position of anterior cranial base. Upper jaw size and the position of the upper jaw, may also be related to the size and position of the anterior cranial base.

Jefferson cephalometric analysis provides easy visual tools to detect the maxillary/mandibular imbalance

Denture Adhesives & How It Work (Karen McDonagh)

Denture adhesive is generally defined as a commercially available, non-toxic, soluble or insoluble material that is placed on the tissue surface to amplify the retention, stability and performance of the denture. This also gives the patient an increased sense of security while wearing the prosthesis. Denture adhesives are sometimes called fixatives or adherents and have been recorded in dental literature as non-medical products since 1935.

In recent years, studies have shown about thirty percent of the population have tried using a denture adhesive product, although less have continued to use it on a regular basis. Patients who regularly use denture adhesives report satisfaction and improvement of retention, mastication ability and an increased confidence provided by using such product. Dental education professionals can be reluctant to advising patients of the use adhesive products due to dependency and the impression it may appear to compensate for a poorly fabricated prosthesis. There are, however, circumstances in which the use of adhesive is of prime benefit in which the professional will then advise according and educate the patient in correct use and safety measures.

How Denture Adhesives Work

In order to understand how adhesives enhance retention, one must first understand how saliva is a key to denture retention. Normally, dentures do not rest directly on the oral mucosa, there is a film of saliva between the tissue surface and the mucosal surface. This salivary film provides retention through the interfacial physical forces of adhesion, cohesion, and surface tension.

- Adhesion is defined as the attraction of molecules to each other. Saliva adheres to the surface of the denture and to the mucosal surface.

-Cohesion is defined as the attraction of molecules to each other and this is observed within the film of saliva. The salivary film on the denture and the salivary film on the oral mucosa cohere to each other.

-Surface tension is seen as the resistance to separation of the salivary film between the well adapted surfaces of the denture and mucosa. Displacement forces placed on the denture are resisted by surface tension forces working within the saliva.

The adhesive product essentially enhances the same mechanism by which saliva contributes to denture retention through these Interfacial forces.

Denture adhesives enhance interfacial forces through a hydrated material formed when the denture adhesive is mixed with saliva or water. There is an increase in adhesion and cohesion as the formed hydrated material adheres readily to both the tissue surface of the prosthesis and the mucosal surface. This hydrated material also possesses intrinsic cohesion properties that have a higher resistance to pull forces than the same.

cohesion properties of saliva. Furthermore, the formed hydrated material increase saliva viscosity, possess the ability to swell when in contact with saliva or water, and flow readily under pressure. This causes an elimination of voids between the tissue surface of the prosthetic and the oral mucosa upon which it sit.
