“Bruxism” in everyday conversation often means any grinding or clenching. In clinical and research contexts, sleep bruxism and awake bruxism are discussed as separate phenomena with different evaluation paths. You do not need to lecture patients on taxonomy, but aligning your team on terms helps consistent charting and lab communication.
What a splint can and cannot do
Occlusal splints (often called night guards) are commonly used to distribute forces, protect tooth structure and restorations, and in some cases support diagnostic assessment of muscle and joint symptoms. They are mechanical devices: they do not automatically treat underlying sleep disorders, anxiety, or medication side effects that may contribute to parafunction.
Patient education should emphasize compliance, cleaning, follow-up adjustment, and that minor tenderness during adaptation can occur. When patients expect instant cure of TMJ pain solely from an appliance, practices set themselves up for disappointment.
Design choices the lab needs to understand
Appliances differ in coverage (full arch versus anterior discluders), hardness of material, thickness in the occlusal zone, and whether the design provides flat-plane guidance or more customized guidance patterns. Those decisions should reflect the clinician’s intent, not whatever default a software preset selects.
Digital workflows for splints often begin with scans or models of upper and lower arches plus a bite record. Inaccurate bites produce appliances that feel “tight,” loose, or uneven in contact. Taking time on the record is cheaper than remaking the guard.
Sports guards are a different product category
Protective appliances for athletics involve different thickness and coverage standards than sleep splints. If a patient asks for “one appliance for everything,” it is worth explaining why a lab-fabricated sports guard and a night splint are not interchangeable.
Checklist before you submit the case
- Specify arch (maxillary versus mandibular) and material class.
- Note existing restorations that affect thickness or undercut blocking.
- Clarify if the patient is in active orthodontic treatment or awaiting surgery.
- Document opposing arch condition (natural teeth, implants, full denture).
Note: This overview is educational. Diagnosis and treatment planning for temporomandibular disorders vary by patient; follow applicable professional guidelines and refer when appropriate.
