A 35-year-old woman came to the dental office complaining of teeth mobility. Objectively, teeth 42, 41, 31, 32 have I degree mobility and teeth 43, 33 have I degree mobility. Tooth crowns are intact. The patient presents with deep occlusion. X-ray shows resorption of the interdental septa by 1/3 of the root height. What splint construction is advisable in this case for temporary use?
