Bite Raising Appliances Splints and De-Programmers
Upper and lower Alginate Impressions to the full depth of the palate and sulcus, including the 8’s, should be taken for all types of bite raising, bite diagnosis or bite rehabilitation appliances. A full arch bite registration of centric occlusion should be taken for all cases (however obvious it appears to be in the mouth). Where the appliance is to be mounted on a Denar Articulator, then a face bow reading and protrusive, right lateral and left lateral bite registrations should be taken.
All working impressions for partial and full dentures should be taken in special trays to ensure best results.
Patients that have exisitng full/full dentures
- Impressions for partial dentures should be taken in alginate as they reproduce tooth and soft tissue undercuts accurately
- Impressions for edentulous cases should be taken in a medium bodied silicon
- Impressions for relines should be taken in Zink Oxide and if a partial an overaul alginate impression should be taken with the denture in place
Where patients have existing full/full dentures then alginate impressions should be taken of them in situ in the mouth so that the arrangement, shape, size and mould of teeth on the existing denture can be copied. Then zink oxide impressions should be taken within the existing denture bases as well as a full arch bite registration. Please indicate the shade of the teeth required as the ones on the denture may be bleached or discoloured. This will save both the impression and bite stages and also ensure that the arrangement, shape size and mould of the teeth on the existing dentures can be copied where required.
The patient's dentures can normally be returned the following day if so required and if the patients require them back quicker the patients can collect them directly from our premises if so previously arranged.
Crown and Bridge Cases
Impressions for crown and bridge cases should be full arch (including the 8’s if they are present) of both the working and opposing model. Impressions should be taken in Impregum for best results (we do not recommend double take silicon impressions for Crown and Bridge cases). For the opposing arch alginate impressions should be taken to the full depth of the palate and sulcus including the 8's if present. A full arch centric bite registration should be taken for all cases, however obvious it appears to be.
For best results, impressions for orthodontic cases should be taken in alginate of the full arch.
Mouthguards, Anti-Snoring Appliances, Sports Performance Enhancers, Nightguards, Retainers, Clench Inhibitors, Bleaching Trays and Tooth Jewellery
Upper and lower Alginate Impressions to the full depth of the palate and sulcus and including the 8’s should be taken for all the above. A full arch centric bite registration should be taken for all cases, however obvious it appears to be in the mouth.
Alginate impressions should never be stored in a fridge or freezer. Storing alginate impressions this way will permanently distort the alginate impression material resulting in an ill-fitting appliance.
