A BULLETIN DEALING WITH ISSUES FOR DENTAL HEALTH PROFESSIONALS



New Bredent VKS HL Attachment
A  dental laboratory owner from Montreal was discussing a treatment plan for a family member with our technical director just recently. This individual stood six feet two inches and weighed two hundred and twenty pounds. With a large individual like this, you usually have a large mandibular to match. They were both concerned about the case and how to go about about it. The lab owner was going to make an implant bar on the existing six implants. He also wanted to incorporate the new  VKS-HL universal male since the advantages of a pre manufactured male were required. This HL universal male is composed of gold, palladium and platinum, which can be cast on or soldered on. The high melting point is 1400 degrees Celsius. The plan was to incorporate six males on to the implant bar and place six metal housings into the over denture. The idea was not to activate all six immediately and have the option to do so in the future if additional retention was required. Case planning is a free service.

Over Denture Stud Snap HL Universal
New From Bredent
Bredent's new Universal HL Patrix

Universal HL MalesThe new male is cast on or solder on. It is composed of gold, palladium and platinum, with a melting point of 1400 Celsius. Available in 2.2 mm or 1.7 mm ball.

Stud-snap precision attachments are primarily used on roots and implant bars for retaining either removable partials or over dentures. the stud snap attachments must be parallel to each other to provide ease of insertion and removal and reduce wear potential. Do not engage labial soft tissue undercuts with the denture base flange, as this will alter the path of insertion and cause excessive wet and servicing requirements. Stud-snap attachments are low in profile to reduce leverage upon the retaining abutments, are easy for patient hygiene maintenance, allow physiological movement of abutments and are easy to service. The advantages to the stud-snap are that they may be used in a limited space since there are two sizes; 2.2 mm and 1.7 mm. They are easy to service and have an adjustable female. They have a vertical and rotational movement. They are time proven and the most cost effective over denture connector while easy to fabricate with less tools or instruments required. The ball and socket movement is kind to abutments and the hygiene maintenance for the patient is very convenient.


Macro Aesthetics in Implants
Macro aesthetics comprises the external facial configuration. The object of prosthodontics is to set parameters that go beyond the restoration and improve the oral and facial composition by incorporating a synergy between the soft tissue, the dentine and the lips. This case study will incorporate Bredent's VKS Attachment System. The goal is to acquire an acceptable occlusal vertical dimension and rest vertical dimension creating a freeway space. Notably the right size implant with a surgical template will ensure functional movements with acceptable macro aesthetics. The lack of freeway space, however, would affect the soft tissue between the upper lip and the nose, by stretching them beyond their limits. the clinical procedure involved a fifty year old male with a hybrid style, screw retained maxillary prosthesis supported by six root form implants. The patient's complaints included an inability to speak properly, clicking teeth while he spoke, an inability to close the lips at rest and substantial amounts of food collecting under the palatal of the fixed restoration. The placement of the implants impeded the freeway space. A health professional team composed of a prosthodontist, an oral surgeon and a dental technologist performed a comprehensive restoration procedure in order to improve the condition. First the existing implants were removed and new ones were placed in strategic locations. After an appropriate healing time, a low profile bar was fabricated to ensure freeway space and that the vertical dimension was measured for accuracy. Due to the patients lack of digital dexterity, the clinician favoured the Vario Stud Snap attachment from Bredent. The system is composed of 2.2 mm castable plastic male and three replaceable dura plast females with different degrees of friction (reduced, normal and high) allowing three varying degrees of retention. A suitable cast frame work was fabricated and the restoration was invested and processed utilizing heat-cured acrylic resin. Afterward the OC normal matrices were inserted in the housings on the cast frame work. When the prosthesis was placed in the mouth, labial support to the lips and cheeks and about 3 mm of freeway space in the anterior region were successfully provided.

APS News Brief
The American Prosthodontic Society Scientific Programme will get underway at the Hyatt regency Chicago on February 18, 19 and 20 of 1999. The theme will be "It's Not the Goals You reach, But the Road You Travel". Some of the seminars will be "The Current status of Colourless Metal Ceramic restoration" by Dr. C. Goodacre, "Overview of Ceramic Systems" by Dr. R.J. Cronin, "Prosthetis and Bio-mechanical Considerations of Implants" by Dr. D.L. Root. There will be many more seminars that you can participate in order to receive your continuing education credits. Don't miss out!

Soldering the HL
When soldering the attachment one should position the male on the post coping or bar with the parallel mandrel and fix with sticky wax. Invest the coping and / or bar so as to get optimal positioning of the flame and solder. Cleanliness is important. The surface of the units to be soldered must be smooth and clean to allow wetting of the metal by the solder. During the heating and actual soldering, the reducing portion of the flame should maintain this cleanliness. The gold solder selected should melt at a temperature low enough to permit flowing with out injury to the alloy being soldered. It should flow easily at a temperature only slightly above the upper limit of its melting range. Afterward, divest, pickle in acid if necessary and polish to a finish without polishing the surfaces of the HL attachment.
