- Free gingival autograft = give by miller
- Free connective tissue autograft = LEVINE
- Laterally positioned flap = GRUPE AND WARREN
- Semilunar coronally positioned flap = TARNOW
- Subepithelial CTG = LANGER
- GTR = PINE AND PRETO
- Pouch and tunnel technique = AZZI
Laterally positioned flap
- TO COVER isolated areas of recession around a single tooth
- Adequate vestibular depth
- Variant = double papilla flap
- Disadv = compromised blood supply
Coronally positioned flap
- To cover 2-3 mm of recession
- Done on multiple teeth
- Best for maxillary anterior teeth
- Pt who have Thick gingival biotype = Good prognosis
Semilunar coronally positioned flap
- Used to cover recession of 1 mm
- Slight recessions in anterior regions
Subepithelial CTG
- Large and multiple areas of recessions
- NELSON graft = better blood supply = bilaminar or subpedicle CTG
GTR
- Maxillary area only
- 5mm recessions = more than 4.98 mm
POUCH AND TUNNEL = It allows for CREEPING REATTACHMENT of marginal gingiva.
- Light amplified stimulated emission of radiation
- RESTING state to emission state. Now it give energy to go back to resting state from emission = CIRCLE FLOWCHART
- CO2 and Nd:Yag = mc used
- TYPES = soft tissue and hard tissue
| Soft tissue | Hard tissue |
| gingiva, tongue, mucosaAffinity towards water and pigmentPrimary effect is heating Diode, Nd:YAG and C02 lasersDiode = 655 – 980Nd;yag = 1064CO2 = 10600 | enamel and boneAffinity for water and hydroxyapatite’Erbium lasers with wavelength 2780, 2790, 2740 |
- Donot requires LA because laser seals terminal nerve endings
- Less bleeding = because coagulation of blood vessels
- Healing by laser is by secondary intention = scar formation as we dont close wound and no sutures needed
- Hence, For large wounds = less aesthetic
- Healing is slower but less postoperative pain
- Less requirements of medications
- AREAS WHERE LASERS CAN BE USED
- Incisions and Excisions =
- disimpaction of third molar = mucopain or benzocaine is applied on mucosa with laser.
- Application of mucoseal = for biopsy
- Dipigemenations
- Gingiva = brownish and blackish
- Melanin = epithelium or superficial layer of connective tissue
- Painless procedure
- Heals within 2 weeks and gingiva appears pink
- No bleeding
- Pain management
- Tmj pain
- Trigeminal neuralgia
- PHOTODYNAMIC THERAPY
- Special use = deep pockets not accessible with instruments and bacteria is still remaining
- Methylene blue or toluidine blue = taken by bacterial cells but not by healthy cells
- Laser will generate free radicals = will kill the bacterial cells deep in the pocket
- Low level laser therapy = Triple L
- Fixed wavelength but you can increase the energy source
- More power= more energy = cut faster in thicker tissue. If thin tissue = it leads to charring of tissue
- LLL is used for healing of
- recurrent aphthous stomatitis
- herpetic ulcers
- Mucositis
- lichen planus
- pemphigus lesions
- LLL stimulate fibroblasts and collagen fibers = healing potential is increased
- Incisions and Excisions =
- Splinting is the process by which you join two or more than two teeth and convert them into rigid and fixed units.
- Hence, this heals the periodontal tissue around the tooth
- Objective = Create an environment where tooth movement is restricted within physiological limits = hence improves the function and comfort of the patient
- Rationale =
- to control the forces on teeth and redirect forces on long axis of tooth = most damaging is torsional and horizontal forces
- To establish physiological occlusion
- To serve as stabilizing force
- To increase patient comfort when teeth are mobile
- To evaluate state of teeth
- INDICATIONS
- To prevent migration of teeth that have been repositioned
- In severe periodontal cases
- In surgical and nonsurgical procedure where teeth are difficult to stabilize
- During orthodontic treatment when you are migrating teeth
- TFO in lower anterior teeth
- Grade 1 and 2 = check and evaluate the mobility status
- CONTRAINDICATIONS
- Grade III mobility without eliminating causes such as inflammation
- Disadvantage
- Maintenance of oral hygiene is compromised
- Phonetics
- Tooth structure loss
- Interproximal wear
- Gingiva and perodontium can be damaged
- BIOMECHANICS
- Convert many mobile teeth into multirooted rigid unit
- Hence, increases area of root resistance
- It alters the center of rotation
- Intrusive forces are tolerated better
- REQUIREMENT
- Have as many firm teeth as possible
- It must not interfere with occlusion
- It must not irritate the pulp
- It must not compromise oral hygiene maintenance
- Interdental embrasure must not be blocked by splint
- Esthetically acceptable
- Must not cause trauma to periodontium
- Easy to fabricate
- CLASSIFICATION
- Temporary = 6 weeks
- Provisional = few months -6 months
- Permanent
- Intracoronal = Into the enamel = remove the enamel and place the splint
- Extracoronal = over the enamel
- According to material
- Bonded = with stainless steel wire and composite
- Braided = like sutures
- Its threaded titanium structure = cover screw
- Above it we place abutment and over it we place crown
- We use implant to replace missing teeth
- No PDL around the implant = directly connected to tooth
- Biological width around tooth = 2mm
- Biological width around implant = 4 mm
- Implant is made up of bio titanium and alloys like aluminum and validium
- Large surface area of implant is MUST = better connection with bone aka osseointegration = given by BRANEMARK
- Time required for osseointegration = less time in mandible = less than 4-6 months = this time is called Loading time
- Sandblasting or acid etching the surface area = better connection
- Earlier we use plane surface = less surface area than threaded surface
- FACTORS
- Density of bone = less density = Primary stability of implant is less and mobile
- Location of bone and anatomical structures
- Posterior mandible = inferior alveolar nerve
- Posterior maxilla = maxillary sinus
- Inferior mandible = mental nerve
- These structures needs to be avoided when placing the implant
- DRILLING
- First instrument used is PILOT drill of 2 mm
- Minimum diameter of implant = 3.3 mm
- Minimum Length of implant = 8 mm
- Different dimensions based on available bone available by manufactures
- Bone must not overheat = must increase beyond 47*c
- Motor revolutions = 800 -1200 rpm must = below this RPM = heating of bone happens
- We also used coolant and irrigant so bone doesn’t overheat
- If bone is overheated = causes necrosis and connection with bone will be impossible
- Bacterial infections and debris must be absent
- 0.5 mm of bone around the implant
- From adjacent tooth = 1.15 mm
- Distance between two implants = 3 mm
- 2gm of amoxicillin before 30 mins of implant placing
- If implant is of 4mm size = drill site must be less than 4 mm for tight fit of implant into bone
- Inflammation around loaded implant when its on function and prosthesis attached to it aka crown
- Types =
- peri mucositis = soft tissues around implant is involved = reversible
- Peri Implantitis = hard tissues aka bone around implant is involved = irreversible
- CAUSES
- Poor oral hygiene
- Uneven forces
- Smoking
- Osteoporosis
- Residual cement
- Signs and symptoms
- Bleeding and redness
- Bone loss around implant
- Probing depth = greater than 5 mm
- Pus formation
- Crown is mobile = because abutment is loosening
- If less than 5 mm probing depth, no bone loss and implant made up of titanium = the treatment is
- Scaling
- Antibiotics
- 0.2% CHX mouthrinse
- If bone loss is 2 mm = we will not open the flap. Same treatment as above
- If bone loss = 3-5 mm = crestal bone loss around implant = regenerative surgery needed
- direct structural and functional connection between the implants and the bone.
- [ hemidesmosomes like structures, no CT insertion, no Sharpey’s fibers ] – the first cell to contact the implant is osteoblast
- It’s normal to have up to 2 mm of bone resorption around the neck of the implant in the first year.
- Implants only have a periosteal blood supply
- No innervation & no proprioception
- Since implants do not have CT [ no shock absorption ] – if there is any traumatic occlusion or excessive force it will lead to bone resorption [ cervically] or the implant might mechanically fail.
