severe erosions. In fact, in severe erosion cases they can do more harm than good. Let me explain clearly and clinically: ### ✅ Why boil & bite splints are not suitable for patients with severe erosions[[edit](https://freemwiki.com/index.php?title=Openai/69357ba5-899c-8006-b1f7-01afc4acae67&veaction=edit§ion=16 "Edit section: ✅ Why boil & bite splints are not suitable for patients with severe erosions") | [edit source](https://freemwiki.com/index.php?title=Openai/69357ba5-899c-8006-b1f7-01afc4acae67&action=edit§ion=16 "Edit section's source code: ✅ Why boil & bite splints are not suitable for patients with severe erosions")] ##### 1. Severely eroded dentition is already unstable[[edit](https://freemwiki.com/index.php?title=Openai/69357ba5-899c-8006-b1f7-01afc4acae67&veaction=edit§ion=17 "Edit section: 1.

Severely eroded dentition is already unstable")] Erosion reduces: * Occlusal vertical dimension (OVD) * Enamel support * Functional tooth height A boil-and-bite splint: * Has uneven thickness * Is soft or semi-soft * Allows the mandible to “find its own path” ➡️ This can further collapse or shift the OVD, which is the opposite of what an erosion patient needs. ##### 2. These patients often need controlled mandibular repositioning[[edit](https://freemwiki.com/index.php?title=Openai/69357ba5-899c-8006-b1f7-01afc4acae67&veaction=edit§ion=18 "Edit section: 2.

Soft splints increase clenching[[edit](https://freemwiki.com/index.php?title=Openai/69357ba5-899c-8006-b1f7-01afc4acae67&veaction=edit§ion=19 "Edit section: 3.

Soft splints increase clenching")] Most boil-and-bite splints are soft EVA. Soft material: * Stimulates the jaw to chew * Leads to increased bruxism * Can worsen muscle tension and wear With erosions, you already have weakened enamel/dentin → not ideal to increase forces. ##### 4. They can change the occlusion even faster[[edit](https://freemwiki.com/index.php?title=Openai/69357ba5-899c-8006-b1f7-01afc4acae67&veaction=edit§ion=20 "Edit section: 4.

They can change the occlusion even faster")] Because erosion patients have: * Thin enamel * Flattened cusps * Reduced vertical support Even slight changes in mandibular position from a soft OTC splint can cause: * Posterior open bite * Shifts in centric occlusion * Changes in muscle memory ➡️ Risk of permanent occlusal changes. ### 🛑 In summary: For severe erosion patients, OTC boil-and-bite splints are contraindicated.[[edit](https://freemwiki.com/index.php?title=Openai/69357ba5-899c-8006-b1f7-01afc4acae67&veaction=edit§ion=21 "Edit section: 🛑 In summary: For severe erosion patients, OTC boil-and-bite splints are contraindicated.") | [edit source](https://freemwiki.com/index.php?title=Openai/69357ba5-899c-8006-b1f7-01afc4acae67&action=edit§ion=21 "Edit section's source code: 🛑 In summary: For severe erosion patients, OTC boil-and-bite splints are contraindicated.")] ### ✅ What IS advisable for severe erosions[[edit](https://freemwiki.com/index.php?title=Openai/69357ba5-899c-8006-b1f7-01afc4acae67&veaction=edit§ion=22 "Edit section: ✅ What IS advisable for severe erosions") | [edit source](https://freemwiki.com/index.php?title=Openai/69357ba5-899c-8006-b1f7-01afc4acae67&action=edit§ion=22 "Edit section's source code: ✅ What IS advisable for severe erosions")] ##### 1.
