An indirect procedure is also known as a laboratory procedure, and the laboratorys location can be within or separate from the dentists practice. What is most important is the sequence of the eruption. No interventions are required to maintain a patent airway, and spontaneous ventilation is adequate. Stretching the PDL applies a pull on the alveolar bone and stimulates the osteoblasts to deposit new bone. Incisors are abbreviated I and are numbered from the midline.

These agents are added to graft material or used alone to effect acceleration of healing or regeneration in hard and soft tissue surgical procedures.
