Thicker occlusal splints are usually rough-cut with suitable rotary instruments, then shaped with appropriate carbide burs or similar cutting tools. Finishing instruments such as Lisko or Liskosil can be used…

How do I cut a thermoformed dental appliance?
Cutting technique depends on material and thickness. Thin retainers and aligners can often be rough-trimmed with suitable scissors or fine rotary instruments. Thicker splints usually require rotary cutting instruments, followed…
How much occlusal thickness is lost during thermoforming?
There is no fixed amount. Thickness loss depends on model height, occlusal anatomy, material, original sheet thickness and how far the material has to stretch. Prominent cusps and incisal edges…
How do I avoid excessive retention on a splint?
Identify significant tooth undercuts before forming and selectively block out only the areas likely to lock the appliance onto the model or patient. Consider model orientation and the planned trim…
How do I block out undercuts before thermoforming?
Fill significant undercuts with a suitable heat-resistant block-out material before thermoforming. Common areas include deep interproximal spaces, strongly inclined teeth, pontic areas and pronounced cervical undercuts. The goal is selective…
Can a thermoformed splint be repaired?
Some thermoformed splints can be modified or repaired using compatible materials, depending on the original polymer and the type of damage. Minor adjustments or additions may be possible, but a…
How long should a thermoformed occlusal splint last?
There is no fixed lifespan. Durability depends on the material, thickness, appliance design, severity of bruxism, cleaning method, frequency of use and whether the patient chews or grinds heavily on…
Is a hard or soft splint better for bruxism?
There is no universal answer. Hard splints provide a stable occlusal surface that can be accurately adjusted, while softer appliances may be more comfortable for selected patients. Hard/soft materials offer…
How thick should a bruxism splint be?
The required thickness depends on the design of the appliance, available interocclusal space, material and severity of wear. Adjusted hard splints are generally made from substantially thicker material than retainers,…
How do you improve retention of a thermoformed splint?
Retention is influenced by model accuracy, tooth undercuts, appliance extension, material stiffness and trim line. Avoid excessive block-out, because removing too much undercut can make an appliance loose, but also…
