Principles Of Prosthetic Treatment Of Periodontitis
Periodontitis (periodontitis) is a chronic infectious disease caused by microorganisms in dental plaque. It progresses from long-standing chronic gingivitis to deep periodontal tissues, leading to inflammation and destruction of periodontal supporting tissues.

Causes and contributing factors of periodontitis
Dental plaque biofilm is the initiating factor of periodontal tissue inflammation, but some local factors, such as calculus, tooth anatomy, irregular tooth arrangement, poor restoration and poor orthodontic treatment, traumatic occlusion, food impaction, and poor Habits and the existence of some systemic factors will promote the occurrence and development of periodontitis.

Clinical manifestations of periodontitis
Including inflammation of the gums, periodontal pocket formation, loss of attachment and alveolar bone resorption

Tooth looseness and periodontitis
The degree of tooth looseness may be physiological looseness, stable tooth looseness, or progressive tooth looseness. Progressive tooth loosening is considered an important factor in the development of periodontitis
Treatment of loose teeth: splint fixation. Splint fixation is widely used as a traditional method of fixing loose teeth. The scope of use of splinting depends on the amount of alveolar bone loss and the degree of tooth looseness. The common splint fixation method is the linear fixation of several teeth, but in some cases, fixation is required in the entire dental arch or across the arch.

Occlusion trauma and periodontitis
In recent decades, the role of occlusion in the progression of periodontal disease has been controversial. Occlusion trauma may cause the periodontal ligament space to widen and increase tooth mobility, but it cannot cause or aggravate attachment loss. Occlusal trauma plays a part in promoting the occurrence and development of periodontitis.
- Classification of occlusal trauma
Primary occlusal trauma: excessive bite force causes damage to normal periodontal tissue.
Secondary occlusal trauma: The periodontal support tissue height caused by normal or abnormal occlusal force reduces the periodontal damage of the tooth.
- Treatment of occlusal trauma
(1) Occlusal adjustment: Occlusal adjustment is suitable for progressive tooth loosening, which can form a good non-central guidance through a gentle guide slope, thereby improving the distribution of occlusal force load.
(2) Correct bad habits
(3) Temporary, temporary or permanent fixation of loose teeth (fixed or removable devices)
(4) Orthodontic treatment
(5) Occlusion reconstruction

Tooth displacement and periodontitis
- Front teeth shift and lip tilt
Chronic periodontitis is accompanied by the progressive resorption of alveolar bone. The displacement of the anterior teeth and lip tilt are usually the outcome of the progressive resorption of the alveolar bone several years later. The mechanism is usually the resorption and extension of the alveolar bone. The result of tongue-out habit and lower lip pressure. When the upper teeth start to shift, the lower front teeth will push the upper teeth outward along with the closing movement of the mandible. When the lips of the upper anterior teeth are tilted, the lower anterior teeth begin to stretch to reach the maximum cusp of the upper anterior teeth
Front teeth shift and lip tilt
Treatment options: orthodontic treatment (Hawley appliance) + tongue wire plus composite splint to prevent recurrence. The Hawley appliance can separate the upper and lower posterior teeth, and the rubber band or wire of the anterior teeth can retract the lower anterior teeth and restore the upper anterior teeth to the normal position of the dentition.
